Uh, look, if you give your kind your phone which is linked to your CREDIT card, you're asking for it. Is it really so difficult to only add a debit card with max of say 20bucks? Even if someone "mistakenly" buys something, the worst they're going to get is losing 20 bucks.

On a side note, love the dangerous goods icon you got going on there.

Look, I have a good amount of respect for your profession. But please don't compare it to math. I'm serious.
