I wouldn't call what's most likely some sort of data analyst a dickhead just for rearranging grocery stores, if only to avoid being negative. There are probably more reasons than one to shift things around. I don't believe it's meant to piss off the customer.
nothing is meant to piss off the customer. the important part is to confuse the customer. Pissing them off is a side effect they dont care about until it hit problematic for them levels of pissed off.
