Yes, no customers, no money.
As I replied to your previous thread under a different name, a girl generates a lot more income to the shop than a single undesirable customer. Banning one doesn’t mean the shop and the girl would have no customers left.
For instance, if Ice of Ginza bans a customer, you think she will be just sitting around ? ;) ;) ;) I’ll put my name down as a reserve promptly.
