Ragnarok online had it. Youd have priests and acolytes sitting in town offering teleport services. Flat flee with tip. If you dont tip, next time they pretend to be afk and ignore you.

The interesting thing is the teleport stays up until the caster enters or after like 8 seconds or x amount of people. So the caster would place a portal down near the buyer and walks into it asap to prevent others from using it hehe.
