I use a lots of RBs. You can check out the profiles and the likes/dislikes to see if it matches your needs. Until after awhile, it becomes all the same ones again and again, some you've seen, which is great that they want to see you again, but you want to try something else, and some never on a month of Sundays. Got quite a few offers from T/Ss, T/girls. As they say, don't knock it till you tried it, but, NAH, no thanks.
Even if you had a HL, and you want a punt today, you can contact the first 10, thru, email,text,call,smoke, whatever, the likely hood is too short notice, not working today, not available or just ignored. So RBs comes in handy, throw the dice and see what you get. Even them, theres snags. Oh you contacted me too late, even tho I given a specific time. I've had one, meeting at 11 at night. contacted her at 6.30, "can't do it now, had a glass of red" WHAT already???? 6.30 so, even tho its a RB, the WG kind of expect to be booked like a normal booking. Some WG use the RB to fill in slack times, but unlike EBAY, they don't watch it till the end and expect to win it, like i do
Yes, its flawed, as other punters has said.
But has its good points of WG you weren't aware off, and hopefully a few quid cheaper
