I did this shop two times and both times did not get paid. The first time I did the shop, I was very honest about my checkout experience and how the cashier was negative but also seeking help and being ignored by other workers who refused to come help with a problem. I was denied pay because the MSC said my time stamp showed that I did two shops at once. Funny, because I only did one shop that day, but I could get no response to that.
The next time, I was very honest about how an associate that I think could have been a manager was unprofessional in the way he talked to customers (me) on the floor and about the terrible condition of the bathroom. That time, I was refused pay because they said my time stamp did not match up to the receipt. Again, I could get no response to my protests.
I didn't do much follow through on the protests simply because it is a $4 shop and not worth the stress to me.
I think that my reports are tossed out because of the negative reports, since I never have had a problem with my times for any other shops. Needless to say, I do not shop Big Lots anymore and I do not do mystery shops there, either.
