Each of us have wildly varying experiences it seems. The madness of tech projects made me feel so helplessly alone. Probably because it involves my own brain and soul rather than a production job, where I can just go, do my task brainlessly, clean and leave everything behind to enjoy the my free time. And customers / colleagues interactions felt nowhere near problematic. It wasn't a special crowd either, a blend of rich tourists and lots of working class at rush hours.

ps: I am not saying thta being the customer interface is easy. Just not in bakeries and some other kinds. My mother was a post office clerk, it was famous for the angered waiting line venting violently on the powerless employees, sometimes physically. I never had to deal with this in the food serving business.
