I’ve done cart balancing enough times to say it’s really not a big deal. I’d rather collect stray carts than distribute the ones sticking out over three parking lot lanes to emptier cart sheds. I also used to feel bad for staff etc, our manager did carts a lot, other stuff etc again, but when I really think about it, fuck supermarkets.

As far as being a nice person or whatever, I will hand over the cart to someone arriving as I’m leaving. I will not take their coin because I use a shim that cannot be retained by the lock to unlock the cart rather than a coin.
