Walmart Supercenter

I have never in my life been made to feel like a criminal as I was last night at Walmart. While leaving the store after buying some things I handed the greeter my receipt as she asked for it when my son and I were leaving. I had 3 walmart plastic bags of items 1 jug of tidy cat, cat liter and 1 case of pop. This lady kept looking at my receipt and said, I don’t think the pop and cat liter are on there. I informed her that they were (I watched the guy ringing me out scan them and my son put them in the cart). She said they are not on there. I again told her they were but she would not give me my receipt back. She then proceeded to allow 2 other shoppers to leave, waiving them by and continued to drill us. Asking who checked you out? I didn’t look at the guys name, just paid and left. She then said that sometimes people «forget» to put stuff that was under the cart onto the belt. Really?! Did she just accuse us of stealing cat liter! She waived another shopper to leave. I again told her that I paid for everything in my cart. Then she wanted my son to check to see what size the jug of cat liter was. Now I’m getting extremely annoyed as people are started to look at me like I’m trying to steal from walmart. I very firmly told her «I’m really getting annoyed right now, I paid for every item in that cart». She finally handed me my receipt still saying that she didn’t see the pop or cat liter. I’m pissed off now, glance down at my receipt and said «they are the fricking 3^rd and 4^th items listed in the receipt!». She was then waiving another shopper by. My son and I walked out completely humiliated as people had been staring at us. I called the store from the parking lot very upset and told the Manger what happened. He said he would take care of it. I can only hope that he did and no one else ever has to be made to feel as horribly as we did. Maybe they should get someone that can read the recepts better to be in charge of something like that.
