Well, if they want to publicly come out and say 'yeah I hate Mexicans too. You guys don't hate Mexicans? Well I demand my money back!' then yeah I'd probably give them their money back or tell them they can have it back but they have go retrieve it from a bank in Mexico. (I have no idea if this issue was about Mexicans or not. It was either them or Muslims going by the odds and I just picked Mexicans because I could really go for a taco.)
