I try not to go in, it only happens right if it's urgent and it's as if you're asking them for drugs, and not buying (with a favor and there's an assumption that the available goods say no). The only branch in which this is the case, there are no complaints about the branch in the 6th MKR and Satpayev (where he was).
But I repeat that this is an assumption and perhaps the choice of sellers / pharmacists falls so that very angry people are sent to this branch)
