I am pretty certain this isn't just me but it's also the older I get the more it bugs me. What is it about a line that causes people to freak out and constantly push forward? We tend to do our groceries on Sat morning and we split it between2 stores, Sprouts for fruits and veggies, and Lucky for the rest. Both are bad but Sprouts is worse, people are so aggressive in the store I almost want to hide. But in both situations what drives me nuts is the way people act in line at the checkout, pushing forward while you're unloading your cart onto the conveyor belt, pushing forward while you're standing there waiting for them to take the person(s) in front of you. 2 weeks ago at Lucky my girlfriend was in front of me standing there but not bagging(they have baggers) and apparently the lady behind me was unhappy so she moved forward and hit my leg with her cart. Not very hard but it was annoying. I turned and looked at her but said nothing, she clearly knew she'd hit me but didn't say a thing. The checker called for a bagger and at that point my GF picked up a bag to start , I was paying with the card in the chip machine and in moving a few inches forward to do that, the unhappy lady again moved forward to take up those inches, and promptly banged into me again. I again looked at her, this time much longer, and again she said nothing. The checker by then seemed to realize what was happening because she pretty obviously said something about thank you for your patience to the other people in line which I took as a veiled stop being pushy to the lady behind me. I see this so often. So is it real, or it just me? My girlfriend saw it happening too and knows how I feel, she thinks it's both, I'm extra sensitive to this behavior, and that due to crowding and stress in the Bay Area, it's more common now. I strongly suspect it's a claustrophobia thing you get into this line where you can't go anywhere and I think people start to freak out and try going forward? We actually saw an older guy in a drive through in Sacramento apparently freak out and rear end the car in front of him twice. The first time we just assumed his foot slipped, but he did it again and the look on his face made it apparent he was VERY stressed out about something.
