Just look at how U.S. culture treats service workers. We best be seated on time for our dinner reservation. No one should wait 15 minutes for their hotel check-in because housekeeping isn't done yet. Oh, and that coffee was ordered nearly 5 minutes ago. And the plumber was supposed to be here at 8.
Your concerns about greed extend well beyond worker productivity. It appears to be the logical extension of believing the individual is sacrosanct.
