I almost exclusively use self checkout because it is quicker, and I felt rushed exactly once because a line was forming. Funny thing is, because I felt rushed I literally forgot to pay and just walked out with a free load of groceries. I did come back the next day and told them, and asked to pay because I didn't want to risk getting banned from that store, as it is the closest one to me. They said nobody ever comes back to do that lmao
