So yesterday I accidentally bumped a customer with a cart because it got loose off the front of my line as I was bringing them into the lobby.

I saw the guy walking into my path, so I tried to turn to avoid him but he still walked directly in front of me, the cart went loose during the turn and I couldn't get up there in time as I was still turning the line and wouldn't of made it in time, and swung off and rolled into him lightly. Customer didn't seem happy and he stared at me, I apologized to him and asked if he wanted my supervisor. He simply angrily told me he wants my name. I gave it and asked again if he would want to talk to my supervisor while he simply walked away without a word and went in. I told my CSR and Service Desk person immediately and they both told me it was an accident and that if he came to complain, they would tell him what I told them. Also reported it to my Night Lead / MOD and he told me it was an accident and that if he called to complain to him, he'd tell the customer just that. 

We cannot use cart straps any longer after one of our younger UCs accidentally brained himself with the store's leather one and got hurt (which I had made multiple suggestions to supervisors and management to remove it from use and replace it as it was a hazard if it was to fly back at you, and to replace it with a bungee type strap like what I use.) My train was my normal amount we are allowed to haul 7-8 total no more. I just hate feeling like I'm going to get in trouble cause of this, as I am always trying to be safe on lot and around customers at all times when hauling or pushing / pulling anything in or outside of the store.
