Ok pretty much any bar... Walmart and other supermarkets take a slightly more supermarket approach.All jokes aside,.go ANYWHERE in the US and after 9pm even your Nan would get asked for ID.
I've never been asked for ID in the US. Even buying booze in Walmart liquor store. It must be you!
The only time I haven't been asked was in Nashville on NYE... And I suspect that was more to do with wearing a T Shirt that said "Nothing some sleep and a good fxxk wouldn't cure" as even the skipper got asked.
Some establishmenta are more strict than others, Tequila Jacks in Long Beach will ask at lunch time.
