Does Anyone Else Feel Guilty Saying No to Cotton On's Donations?

Is anyone else getting more comfortable saying "no" to the constant upselling at Cotton On registers? You know, the whole "Would you like to add $2 to donate to [charity]?" or "Do you want to add a bottle of water or a tote bag?" I used to feel guilty about declining, but now I just politely say no without overthinking it.

Does anyone else feel the same, or am I just a terrible person for not caving in every time? Curious if others are in the same boat!
