Second and Seneca Garage

We parked here on Sat at 7:15Pm, saw the sign it said weekend special $ 10. We came back at 9:50 and the garage door closed. We called security. The security guy said he can only escort one car at a time. Our friend parked her car right next to us and he still did not let her in at the same time. He said it is their policy, for what? Who knows. He then wrote us a bill for $ 30. Yup, not $ 10 but $ 30. He said he must charge us by hourly. We thought only $ 7 per hour after 9PM. He said no receipt since we paid in cash. Our friend later displeased with the price n he then ok’ed to take $ 28 from her. I don’t know how much the people behind us paid, and I heard that there r other groups waiting at different garage for him to open the door as well.
Obviously the sign is not clear nor says anything like «$ 30 if pass 9PM». I should not pay in cash last night but take this matter to the management. Too bad. Please do not park here or read carefully whatever is posted there, if they do post it. I, my friends, family and some of people reading this won’t ever park there again.
