Just bought a 2m section of flexible tube for a gas stove, and the sales clerk asked first for my phone number, to which I replied “I don’t have one”. Then she asked me for my name, to which I replied “I’ll pay in cash”. She then insisted it was so “the cashier will call you by name”, to which I replied “I’m not giving you my name, I’ll pay in cash”. [Edit: she apparently got a bit upset when I refused to give info, but ended up entering “no name” according to the receipt]
Am I wrong for not wanting to give personal data for an item paid in cash, in person? No other hardware store ever asks me for my personal info.
They don’t care either way.
They are working retail jobs and harassing you for personal information is just one in a long list of things they have to do to get paid.
I myself just go with a “no thanks” , “I’m good” or sometimes a “I don’t believe in (thing they are asking for)”
