Always park on the same side you are shopping. If, for some reason you can't then shop a couple of cart lengths ahead or behind so you don't block the aisle. And unless you have a grabby toddler in the cart you should be parked right against the shelves to maximize passing room. And don't park right by a pillar or $#*@ing in-aisle display. And, store owners: no more in aisle displays. I want to go through Kroger on day and count the obstacles. I know, your research says the slow down and weaving increase sales. But you have so many that I skip whole aisles rather than browsing. (I feel like Frank Castanza and the airing of grievances. I got a lot of problems with you people! And now you're gonna hear about it!)
The only thing that makes it worse than that, is when they do it in the freezer aisle,and prop the freezer door open with their body while they struggle to spell out the word “the” on the label...for (literally) ten minutes straight.
