I use to waitress at a club for a couple years and I was allowed to have a couple drinks. I use to drink like a fish and I still love drinking alcohol but I've slowed way down. I'd say I would drink 2 mixed drinks everyday that I went to work. I never became ill from drinking any of those mixed drinks. My suggestion would be to ask them to not include any garnish in your drink. The fruit isn't really necessary, just ask during your order what is included in the drink and exclude any fruit or olives ect.
