That blocking of the aisle thing really bothers me. Also walking slowly down the middle of the aisle, whether it be supermakrets or whatever. WHn I go to the store, I know what I need. Being single and living alone, I don't cook too much, so for me shopping is a breeze. Get in, grab the essentials, get out.

About those "loyalty" cards. I've never filled out an application for them. When I move to a new area with a new grocery store, I wait until a busy time, go to a checkout line, ask for an application after everything ha been rung through, and the person lets me have the card if I say I'll drop the app off later.

Edited to add: One more pet peeve. Didn't happen at a grocery store, but Fry's Elctronics, so still a stor with carts. I hate it when people get close to me when waiting in line. Granted I have personal space issues, but I think this situation was ridiculous. The lady pushed her cart next to me and she was physically a foot behind me. The line moved, I moved, she moved, and that darn cart was right next to me again. I like to give the person in front of me plenty of room, unless the line is so backed up I threaten to block the walkway (I'm looking at you, Costco on Tatum in Phoenix AZ at 11am who had 2 checkout lines open).
