That doesn't sound good at all. All that pressure selling sounds nasty. No offense, but when I return to Canada I will avoid the snack country like the plague. It seems like it adds unneeded stress to both you and the customer. What a sad world we live in.
Let me add that it's not something I blame you for. Those large companies that are trying to squeeze every dime out of us are the ones who cheese me off! Kudoes for making the best of a nasty situation. Pressure selling is also not east, so good job for doing your best.
