Only a couple times...a bit too cheap for me.
FWIW: I was shocked too when I found out they can sue the store for damage done by the carts. So we just pay them without going to court. The sign does do the job though as most people don’t realize the sign is just bullcrap trying to keep them from complaining to us.
And we will even tell them the sign says not responsible, but if they say that’s BS signs don’t mean anything under the law in this case...we ask them for a receipt for the repairs. If “reasonable” we pay it.
“FWIW: I was shocked too when I found out they can sue the store for damage done by the carts. “
Where did you find that? Law office sites say otherwise.
