I was at the supermarket to buy some pears and I couldn't find a bag to place them in so I asked one of the people who worked there if it was possible to get me a bag when this happened -
Me: Can I please have a bag for these? *shows pears*
Employee: Yes, bear with me one moment and I'll get you some
Me *with pride*: Did you mean 'pear'?
Employee: *awkward smile*

I don't regret anything.
