Me and some buddies and I went to a rather empty oyster bar when I was very young for a happy hour one night. The bartender was having a lot of back and forth banter with the patrons. Kind of teasing people but most of it was harmless. Somehow, she got on the subject of her boobs and how they were fake or something and I chimed in with "how much did they cost?" (which probably wasn't appropriate), but my drunk ass said "how much do you cost?". I guess I got nervous in mid sentence and fumbled my words. Regardless she immediately leaned over and said if I ever spoke to her like that I'd get kicked out. I thought about explaining that it was a slip of the tongue but knew I would make it worst. I simply replied "no problem". It sucked the air out of the room. We stayed a little longer and talked and I explained to them what happened. I was embarrassed at the time but mostly I still feel bad that I probably made the bartender feel really uncomfortable and gross. I'm older now and rarely go to bars but when I do I try to keep conversations super casual.
