not ALL stores have a machine and you still are out in the freezing cold and 100 degree heat and no respect from ANYONE not even co-workers at most stores. In my experience working retail for almost 8 years I know what it's like!

im a cart pusher and that machine well i cant ever use it because i let the older guys (60's) use it because they cant push them, ive use the machine like 8 times in my 11 months there

its really not all that hard if you have a rythem going but you break that rythem or you dont see a small obstruction, or one of the carts jam you're fucked, they will go everywhere you have to race to catch the baskets if you hit a single car with a single cart you can get fired ive seen it happen.
people are rude, they leave their trash in my carts empty wine bottles (i dunno why they empty the wine into something then chill it in a cooler) thousands of empty beer cases, empty beer bottles cuz they just cant wait to drink or throw their trash away untill theyre home... i deal with dirty diapers on a daily basis i sometimes toss them back at the customer who left it in there they never say anything to me though.

my final complaint... OLD PEOPLE! if youre old you shouldnt be on the road period... ive had so many close calls and people just cant seem to see my huge line of carts if they have glasses thicker than donuts...
