I've attended this space since 1150 was still in business. When the club changed hands and names, I still continued to frequent it. After my last experience, never again.
I have attended 6 Liquified events at Opera this year, I average about 10-12 for the year. I went to the Markus Schulz show and paid for my first few drinks with cash. As I was running low, I wanted to use my card. I went to the bar and was told there was a $20 minimum for card purchases so I opened a tab. The bartender took my card AND license. When I was done drinking, I attempted to close out my tab. After signing the receipt, the bartender advised me that my signature on the receipt didn't match the signature on my license (mind you, the signature on my license is from my first driver's license when I was sixteen, I am now twenty-seven). I asked the bartender how I could have a fraudulent ID to match the name on the debit card. He replies, "Oh, anyone can get a fake ID on the street."
I ask to escalate the issue to someone else, he tells me that he's the first and last stop. Not really wanting to make a scene, I sign my credit card slip THREE more times (for a total of four) before the guy decides to give me my card back.
I have dealt with a lot of crap at this venue from the staff, but this takes the cake. Their focus is clearly not on the customer, I would be wary before patronizing the establishment.
