Get separate clothes for work, keep/wash them separate, rub grease stains with dawn soap before you wash, bring a work bag with deodorant/clean clothes/whatever (especially if you have plans right after work. mine has ibuprofen, deodorant, gold bond, hair ties, extra bandanas, weed, and face wipes at all times), dont fuck the servers, do not date the servers, get good shoes (insoles if you need them). Good shoes will save you. Dont wear them outside work. They are work shoes only.

If you dont smoke, have a lighter on you. You'll make fast friends with the guys who do smoke.

I cannot stress this enough: GOLD BOND EVERY INCH OF YOUR BODY. Toss that shit in shoes for athletes foot, rub it on your junk to prevent chaffing, thick thighs chaf like fuck, underboob, everywhere.

Tl;dr good shoes, gold bond, dont fuck/date the servers, more gold bond, work bag, keep work attire separate, g o l d b o n d
