The ruling on such matters usually is that if the majority of the transactions carried out are halal then a small share of haram is tolerable (provided that you personally are not involved in the haram activity, and do your best to segregate the revenue from such activities and distribute the tainted portion of revenue as charity without hope of recompense).
From https://islamqa.info/en/101775
Renting a shop to someone who sells permissible goods in it, such as
men’s perfumes for example, and other goods that may be used for
halaal or haraam purposes, such as cosmetics, depends on what is
usually the case. If most of the products are of the second type, and
most of the people in that country use them for haraam purposes, then
it is not allowed to rent the shop to a person to whom this applies,
so that you will not be helping in something haraam, because Allaah
says (interpretation of the meaning):
...
But if what usually happens is sale of permissible goods in the
permissible manner, then it is permissible to rent the shop, based on
the usual situation, and so as to ward off hardship and difficulty,
because most sellers cannot avoid selling things that may be used for
halaal or haraam purposes.
