I use paypass & quite like it. I haven't had any sales people/ shop assistants automatically assume, most times the opposite b/c have a chip card, so they go to automatically insert it - either way I don't mind but given what others have said about the three day clearance and living week to week, I can understand the reason to opt out or not want to use it.

I don't use my VISA debit b/c I have a VISA credit card but I know my sister will be happy now - thanks for the information
