But in all seriousness, if you have to have a social life, limit your spending on that stuff. Restaurant and bar tabs can add up quickly. Budget, limit your drinking, and if you don't wanna limit your drinking, at least do some cheap drinking at home first.
We used to drink a quart of cheap beer in the parking lot before we went to the nightclubs. We had spares in the trunk for later if we sobered up too much.
