I noticed recently when I'm checking out at the store, the cashier will ask for my email address, so that the store can send me flyers, coupons, and promotions. In other words, junk.
What I've tried:
Avoid interacting with cashiers that I know will ask for my e-mail address. For the times I do get asked, I usually respond with:
No, I don't want to give out my e-mail address.
At that point they attempt to try and convince me by telling me all the benefits of allowing them to have my e-mail address.
In an effort to speed up the conversation, I usually give in, and let them have it.
I'm aware that I can hit unsubscribe when I get these emails, but I don't really know what happens to my e-mail address afterward, is it removed from their database? I don't know.
How can I, in the cleanest, shortest way decline to give out my e-mail address without inviting questions?
I don't want to yell, carry on a long conversation (there are other people in line, after all). Simple and to the point.
