When I was at the store I rushed ahead to put my items in front of the cashier.
I'm confused. Why did you feel that need to rush like that?
Well I saw old people moving slowly, so I hurried to get in front of them so I wouldn't have to wait so long.
I get why you might always be in a hurry. But it isn't good to cut in front of people just because you think they'll be too slow, because that's pretty rude.
I just want to get out of the supermarket quicker. I don't understand why you are against this.
I'm against it because skipping ahead in line or running to get in front of others is pretty rude. I know it's a little annoying, but part of living in a society means having to wait in line sometimes.
