I feel older than dirt accidentally went to a college type bar

I had no idea the place was a college type bar/club. Never been there before but a friend wanted to check it out. We go and grab drinks and hang out by the bar and I swear nearly everyone was college aged then there was us. Needless to say we didn't stay there super long. We were the 40 year olds at the college bar....not a good look. We moved to across the street to a bar we go to often that's more geared towards our age group.
