It appears to me, that Walgreens associates are more interested in following policies, than serving customers. Men now have to signal for assistance to purchase razor blades. (Meaning: Ring for assistance, WAIT, 'assuming someone actually shows up', and get them out of the case.) Now, at least at the GRAND AVENUE location in St Paul, MN, they then don't even trust you to put them in your cart with everything else. They hold them at the counter, until you are ready to pay.
I'm not going to work that hard to be their customer. If you are that worried about shoplifting, consider the number of customers like me, that just voted with their feet.
