I've worked to develop friendships with the PC's and some staff in my neighbourhood store and some of the flagship stores. They then always try to help me out, in finding stock, transferring items from other stores and giving me a heads up on arrivals of interest to me. One nice fellow used to set aside bottles for me, but was transferred to another store. On one occasion, I had to have a chat with the Manager about a interpersonal relationship challenged staff member manning the service desk; that individual was moved to general cash and eventually moved out.
The LCBO will always be the LCBO, but most people are or can be good people, if you give them a chance. Most are just doing the best they can, to do their jobs as they know best. Being respectful and asking for their help generally works.
