I am assuming OP had the money, but needed to transfer it to another account before they could use it. And if the wifi had worked, it wouldn't have been a problem.

I guess I just read it as this being lunch/a snack and OP wanted to get dinner later. Still kinda dumb, though.

Ahhh. That harkens back to a simpler time, when a shopkeep would pay you a few bucks to sweep his front stoop and give you a sandwich. Now, the IRS demands a cut of any penny earned and will spend ten thousand dollars to collect two dollars in taxes.

#6 I'm thinking something like transferring funds from a savings account to a checking account

Cards will generally auto transfer in that case. At least if you have overdraft protection. It will pull the extra funds needed from savings, and then charge a small fee for the process.

I read the fml as ' after paying for my drink and my snack in order to use the wifi, I can no longer afford to buy something larger for my dinner' rather than 'without the wifi I am unable to pay for the food I've ordered'. Don't know if that makes more sense to you?

Very very few cities have that. Only some major cities have them, and only in certain areas. It's usually pretty choppy anyways
