I don't think bitcoin is fit for this situation. transfer fee would be too high for a small amount of money, other kind of altcoins would be great.
anyway, things are going wild there. happy to see cryptocurrency's being applied
If you'll be doing transactions below $100 I can't recommend you using bitcoin as a payment method but if you'll be doing big transactions on mall specially on a shopping trip bitcoin would really benefit you because sometimes people tend to exceed their credit cards limit for a transaction so bitcoin would be beneficial for that.
