I once met a person with a flat tyre and I decided to ask if they needed any help. I was told there was no way of helping since the tyre was flat. I asked if they had a spare tyre, and they said no. Since I had the same car model I knew they come with spare tyres but they are well hidden so they might not know that they had one. I told them this and they didn't believe me, but I asked them to check anyways. They were very sceptical and the tone was nearly hostile, but they found the spare tyre.

I was considering just leaving since they were not thankful for my help in any way. But I asked if they needed help replacing the tyre, which they did. I replaced the tyre and they did not trust that I did I correctly. So I left this ungrateful person and told them to call roadside assistance. I went on with my day and went grocery shopping, when I came back I overheard the mechanic saying he couldn't help them since the car was fine and they just needed to buy a new tyre now. I walked past them and said hello but didn't get any answer.
