Fair point, Sunnylea57. Seems like you had a run in with abit of a character. We should (as customers) not have to be subject to behavior like that.
I'd suggest chatting with the store manager, if you wish. He can either offer the offending individual some coaching or discipline or both. And sometimes, folks are just in the wrong job, relative to their skills sets. I once had a similar run in with an LCBO clerk. When I mentioned it to Store Manager, he was not surprised and thanked me for coming to him, as it gave him the information he needed to deal with this employee, in a union environment.
