If you work in a busy department store, do you chat with friends when they shop?

In one of my first jobs, I was a cashier in a department store. I was pretty good at my job. It was the old kind of cash register where you had to press a combination of keys all at once to get the price to pop up on these little numbered tabs in the window. Then you had to turn the crank at the end to make the drawer pop out. (Oh ya, I'm older than you think). We even had to make change by counting backwards (oooooooo, can you do that?) I was 16. One day during the busy Christmas season, my boyfriend came to my register to check out. I got talking with him some, but the worst part was he flustered me so much (you know how when you're 16 and boy crazy your hormones go crazy and so does your brain?) that I got all mixed up and couldn't make the cash register work right. It was me that wasn't working right. Another girl came and helped me with the cash register. Now I get annoyed when cashiers fool around and talk amongst themselves, but I should maybe be more patient because I was there myself!
