I walked one avenue to the ATM, withdrew $100, and walked back to the laundromat, and was relieved to see the glass on the door hadn't been cracked.
I'd come in to pick up my laundry, which was about $13. When I tried to use my debit card, the counter lady told me they had a $15 minimum for debit cards. As it was early in the day, and my brother was scheduled to be in court sometime soon, I wasn't in the mood for this. So, after taking a moment to silently register that she was serious, I strode out and swung open the door full-force until it hit whatever door-stop mechanism they had installed.
The counter lady seemed unusually subdued when I got back.
