Walmart is open 24hrs.
Not all of them. And yes, really, and yes, I’m sure.
As for mfms experience I don’t really know why updating the register would have taken more than a few minutes, and if it was going to be more than that they should have paged it overhead so shoppers would know. Are you sure they didn’t do that?
They didn’t do that. There was no warning. I’m 100% sure.
Are you 100% sure that you did not enter the store at a time when the store was not technically yet open?
If so, you should be able to tell me what time you went into the store and what time the store you went went into technically opens.
