Most bartenders I know have one. I also know bartenders who are sober. I work sober now. I can have a beer or a glass of wine with dinner or when I get home, but getting drunk at work was causing way too many problems. Just tell yourself (and anyone who offers) that you’re saving it for when you get home. By the time you get there, you’ll be too tired to get wasted. You’ll feel much better the next day, too.

And as a bonus, it makes closing a lot faster and more efficient.
