-Managers (though not all) were far more concerned with their problems than that of their staff, which oftentimes made for a somber, demoralizing environment.
-Micro-managing was also a huge problem. It's confusing to be in a heavily-independent atmosphere with someone sporadically breathing down your neck whenever they are in a bad mood.
-The money can be good, but the general upkeep involving this job is very expensive. You have to be really, really smart with how you spend and save your money. I spent an unfathomable amount of my tips just paying for cab rides home from work at 4am, take out/delivery (no time to buy groceries, zero energy to cook), constantly buying new work clothes, chiropractic treatments (kills your back), and most of all-- going out with co-workers afterwards and being careless with bar tabs. 'Tis a slippery slope!
-The hours are not regular, despite what you may be told-- especially in slower months. You have to be VERY assertive with your scheduling manager(s), as they may have to be reminded 4 or 5 times that you can never work Wednesday nights, or that you absolutely have to be full-time to be eligible for insurance.
