Best Nails

Had a pedicure done a week ago, colour is already chipping. Upon entering store I was pointed towards their nail polishes to pick a colour, which I assumed were shelac. I was advised when they'd finished that the shelac colours were on display elsewhere in the store which is what I wanted in the first place.
When i went to pay the gentleman who served me said their eftpos machine was "broken". Why should clients need to withdraw cash and incur eftpos fees so these businesses can avoid paying taxes? I won't be returning to this store.
