Every retailer is going to try to sell you things. Every retailer is going to require their employees to try to sell things. Politely refuse and then go home and enjoy what you did decide to purchase. If the majority of people agreed with you, and always said no to all of these "add-on sales" at the register, then the company would not be able to justfiy the money they spend developing, advertising and training their employees on these sales techniques. Since they continue to do it, I can only assume it's because there are a lot of people out there who do want to partake in those services, and that those questions at the register are for them. I'm not going to sign up for a credit card either, but it's okay if other people want to. And they do, or they'd stop asking ya. And refusing to shop there is causing more damage to the job security of the cashiers you claim to sympathize with than helping them. Whatever message you're sending by your boycott is not being received by that store in any marketable way, so all you're doing is reducing sales in one store. Even if you got you and all your friends and family to never shop there again, they would still ask for credit cards. They'd probably just drop that cashier's hours from 30 a week to 20 due to lack of sales.
