Police aren't looking for this. It used to be the Hay'a, islamic religious police, but they were stripped of all power. It's still frowned upon culturally so you don't flaunt it and there's zero public display of affection, but...like...Tinder is very active and there are known coffee shops/restaurants/spots where singles meet.
When I was looking for an apartment, it's one of the first things the sales clerk told me there..''we sell ''special'' drinks at our restaurant, and if you want to have friends over it's all at your discretion. This is a private gated community.''
I mean...it's not Montreal or San Fran or Hong Kong or even Dubai, but it's not as bad as most think either.
You can find any alcool or drug you want if you dig enough.
