I wonder why dudes who work in stores don't just keep it 100. Like if there were only 2 pairs of my size in shipment and a customer asks for that size, I'd have no problem bringing it out and telling a third customer asking for the same size "sorry fam that's me". Lol no ducking or walking in the opposite direction required
Employees need to let go of the notion that customers will be mad if they catch you buying a size that anybody from your store said they didn't have available for sale. Reason why is because most employees know when a shoe is getting copped by a coworker and when that size is requested the right thing to do is say that size isn't available.
Now if the size requested by the customer is being held to flip, like a size 11 employee denying the availability of size 8 OVO 10 to a customer so he can hold for his boy who's coming in to cop 1 minute before closing in all cash given to him by the size 11 employee the day before... that's messed up
