To avoid going to withdraw cash at the ATM machine of my bank. This represent withdrawals of several hundred dollars on a nearly regular basis. I do not want to fall in paranoia, but on a long term it could be suspicious. Usually I do not need cash, I pay with card. Paying with a credit card, if the provider has a discreet business account, would be easier for me and more discreet. But from the view of the provider, it could be more complicated to manage the income.
