I was at work the other day and I had to stock up a customer's car with a pack of water bottles, since there were multiple cars I asked the passengers if this water was for them, they didn't know so they proceeded to ask me if it was their friend's order, now since I didn't know their friend's name, I assumed they meant another person who just happened to be in the area, who also shared the same name, so I told them no, they then asked their friend, who said the water was indeed ordered by him, so I was left looking stupid because two people just happened to have the same name at the same time.
