how do we as atheists feel about companies using customers to donate money?

[comet]

for example i went to taco bell and they said would u like to donate a dollar to "help a local teen graduate highschool" and i hate when businesses do that because apart from all the rumors that very little of that money actually makes it to a charity, i feel like if they want to donate money they shouldn't piggy back on their customers, instead they should donate their own money.

and the thing is i do believe in chairty and i myself donate quite a bit where I can, but when I go out to eat I go for food not to be cheeped out into donating 1$ for a charity that I can't even find a website for. Also it's tough because my parents are from india and my skin is brown so if the people behind me in line see i say no to the donation they will say "oh that cheap indian didn't donate" - so I feel pressured to because my people have a bad enough reputation as it is, aside from all the others who think I am some how linked to al-quida, but have they have no idea that I served in the US military right outside of highschool and how much money i do donate every year.

past a non belief I got little in common with you.
