No, these three beer oases don't take credit cards, but they do take you at your word. If you don't have cash and don't want to use the ATMs on site, the staff will provide you with a self-addressed stamped "karma envelope" so that you can mail in your payment — and tip! — later. "I'd rather take that loss than pay credit-card fees," explains Paul Nashak, managing partner of the company that owns all three places. And, no, they won't make you wash the dishes.
