I am a bit baffled here. Visiting Jelly Roll’s bay on Broadway listening to a phenomenal band and paying $10 cash per beer. But when we put it on a card the price was lower. Asked the bartender why and was told every bar on Broadway rounds because they run out of $1’s. This seems pretty sketchy to me as we tipped on top on the cash every time. Is this genuinely the way it’s done on Broadway now?
