Where I live in Ireland, multiple towns near me have new nail salons setup for manicures, pedicures etc. Thing is though, almost all of them have big signs up saying “cash only”. A lot of the time its not busy or they have no customers yet new ones open up every month. Its almost certainly a front. The cash only thing is likely so that its easier to avoid tax or launder money. The government was looking to make cash only businesses illegal and must be able to take card payments too, but that legislation is probably a few years out yet.
