What do you think are some of the most annoying things some people do?Could it be someone who is a very discourteous and even an unsafe driver?
Someone who leaves a very small tip or none at all to a hard-working server, when the tip was not included in the price of the meal?
Someone that swears or is a bigot and you are subjected to having to hear it before you can leave or ask that person to stop that talk or to try to educate that person (that last option is hard to do in practice because of that person often having a lack interest in hearing another's viewpoint)?
Remember, even if you find something annoying, perhaps something you do is annoying to others!
