(If you haven't heard of them: in the 1800s London, one happy customer would get their ice cream, lick the glass clean and return it to the vendor, who would refill it and give it to the next customer. Perhaps the best way to spread tuberculosis, which the Penny lick did very well on until it was banned in 1899.)
Sadly wiki only has an article on this in Polish, but google translate does a decent job:
This was a problem if you wanted both mayonnaise and mustard. It wouldn't be polite to contaminate one with the other, plus you might get bits of lettuce and bread in the jar.
So we were taught that after putting the mustard on the sandwich, rather than dip the dirty knife in the mayonnaise jar, we should first lick it clean.
That would give a pretty good head start on quality.
Medical episodes cause a cascade of ill-circumstance tumbling once-stable positions into the streets: "...who is now in difficulties through ill-health..."
Retirement a binary condition ill-suiting putting purpose to people's lives: "I’m lost, I’ve been put off my perch"
Substance abuse inures the senses of those who have given up, and thereby tragically reinforcing cycles of abuse into future generations: "...early acclimatizes her infant to the fumes of tobacco and alcohol"
Poor squeezed by land prices into living in the flood plains, with predictable disastrous consequences if their unlucky number comes up: "The sufferings of the poor in Lambeth, and in other quarters of the Metropolis, caused by the annual tidal overflow of the Thames"
"Improvements" displacing common people to the benefit of rentiers, and destroying the micro-culture of a neighborhood: "As a matter of fact, the inhabitants of Church Lane were nearly all what I may term “street folks” – living, buying, selling, transacting all their business in the open street...condemned as an unwholesome over-crowded, throughfare, and the houses on either side are now almost entirely destroyed, and the inhabitants have been compelled to migrate to other more distant and less convenient parts of the metropolis"
Industrial disruption comes at a steep cost to those whose lives are disrupted and swept under the inconvenient rug of the disruptive effects to individuals, even military veterans, to the benefit of the overall economy: "...two boardmen who seemed worthy of a better position..."
There are some, but too few, bright points, considering the progress we trumpet ourselves possessing. Some parts of the human condition remain quite thoroughly embedded within our civilization's mien for the time being.

Now the 2 1 7 and 6 for the peppermints is an odd thing. I presume it is the price but my first effort is: 2 for 1, 7/6 ie 2 for the price of one for 7 shillings and 6 pence but that was quite a lot of money. Another photo show a bowl of ahem beef leg soup for 2d.
Pre decimalisation British currency was: £1 = 20 shillings, 1 shilling = 12 pence, penny was written as d (denarius, the s for shilling is really sestertius and the £ is L for libra - all loosely Latin).
Now days, of course, London's streets are all choked with parked cars, creating a less than welcoming environment for cyclists and pedestrians. And horses.
Alhough these days, the Police generally don't bother trying to crack down on illegal street traders and other minor crimes.
They went from house to house asking for old umbrellas, and from two old ones they could make a new one.
"Mushfake" is a very interesting word. It seems to have first appeared in underworld slang back in the early 19th century in England. "Mush" by itself was, in that period, slang for an umbrella, from its similarity in shape to a mushroom. The verb "to fake" during the same period was criminal slang for "putting something in shape to sell by covering its defects." So a "mushroom faker" or "mushfake" was a con artist who repaired discarded umbrellas just enough to make them briefly functional and then sold them on the street, preferably during a downpour. http://www.word-detective.com/111703.html#mushfake
Nearby is Yeovilton - don't even think of trying to derive that one!
Now we commonly sport sailors' underwear (t-shirts) as outerwear in public, and even in places of business! And low-class rugged laborers' trousers (denim jeans) are worn about by merchants and businesspersons, and can be expensive, high fashion.
Clothes are weird.
