Had a large group coming and they closed a half hour early. Said it was their right to close when they want, but seems like a money grab. $15 for one hour and $11 for 30 minutes. So they make more per person per minute and they do not need to pay their staff for that 30 minutes. Shady business practices and I will never go again. Customer definitely does not come first.
