I think saying "Don't enjoy it? Don't do it!" is misunderstanding the gulf between those two counts. The entire service industry would likely grind to a halt if people actually took that advice.
I don't understand the point of what you said here.
Q: When you arrive in a restaurant and your server pitches up and says "Hi, how are you?" in a super-bright, ultra-cheerful way, do you immediately think:
a) wow, they genuinely enjoy serving people or b) they've been told/taught to greet customers that way, _every single time_
?
It was obviously part of the job and nothing personal, although we were nice and not assholes in any way. Some people find it super cool, I just found it the most fake bullshit ever, and really hope they weren't actually forcing their staff to drink with customers but rather encouraging or just allowing it.
If I have to think about the staff's conduct, good or bad, usually that means something is wrong.
