At the dominant pharmacy/convenience store in my area (Shoppers Drug Mart), it can take up to 12 clicks to self-checkout, depending on what garbage they're upselling on the day. I counted them.

I refuse to use them, and (annoyingly, I know) let the cashier know why each time as they're checking me out. I feel bad for the poor cashier but unfortunately for them, they're my only interface to the company.
