Take your pick. Say you like the ka not so mjuaji 21 year old in Buruburu in need of a good smash. She is willing to be hosted all for 1500. So you ask admin for her digits and s/he starts by telling you that the girl expects 3k for a hookup. You agree and pay your 1k hookup fee and admin sends you their number. You suddenly realise that this is 21 year old is in Huruma or Pipeline or Zimmerman. They also tell you as a matter of fact that they can only host. Sasa ukiwa na kimbelembele ujipeleke we'll read your stories on the news or mtandao. But if you smell a rat and try to tell admin that they gave you the "wrong girl" you realise that they don't respond or they blocked you. Na hivyo ndivyo 1k = 1 bag of cement and a few kilos of 2&1/2 inch nails will disappear. If not more.
