I have a scar in my foot remembering me not to wear flip flops to clubs!
Why not they simply use plastic glasses??
I totally agree with you but would you pay 15euros for a vodka in a plastic glass?!
I too have 'war wounds' from the glass on Ibizan dance floors!!
I have to say, I always wear flats out clubbing but I'm nearly 6' tall so I feel like a man in drag with high heels on anyway!!
