At a hotel and needed an extra room key so I went to the front desk. The guy behind the counter was nice and struck up a conversation when suddenly one of his teeth fell out and bounced on the counter.
Without acknowledging it at all he clapped his hand over it and kept chatting. It was so unexpected and random that I almost fell over laughing and had to quickly change the subject to keep my composure.
He was a normal 30-something year old guy too and if you had asked me what condition his teeth were in just a minute before I would’ve said they looked healthy.
Great conversation otherwise. He had lots of stories to tell about his trips to various Asian countries.
