People tend to check in during these times:
Watch out for Sundays, when one woman comes in and takes up 7 dryers at once for her "laundry service".
The dryers are cheap (10 mins per quarter) but don't work well, so it actually costs plenty of money and time.
Not as fancy as the laundromat on Nassau and Jewel, but dryers are 10 mins per 25 cents!!
Sit in the chair outside for the true Samoobslugowa experience.
