You've got a point here.
I started punting in Amsterdam, and there was something about being able to wander the streets, choose and be in there 5 mins later
I didn't have the confidence back then to have done something like a private brothel, where they bring all the ladies in at once - but I can see the advantages now
The internet has ruined it for speed, but I think it has massively improved it for safety and quality of service
Not reading reviews and posts, my favorite one back in the day was perfectly safe, run by a British woman and always had 3 fun willing girls, never had a bad bunk up there. Most were just the same.
There was one price, no set time, you might get a knock on the door if they were busy, otherwise as long as both were happy in the room, no rush, and as I liked mornings it was rarely busy.
I do not think the internet has produced better service, you might have some idea what to expect, but there are no guarantees as pictures tell lies.
Take Sunday for instance, had time, was in the mood but searching for something suitable, regs were not around, just spoilt it, I lost interest after a while and judging by the big drop in review numbers, I am not the only one.
