There is a group of African women (A female version of Lookee Lookee men!) what they do is walk up to you take your hand make friends ask questions etc and then the put a bracelet on your arm!!! Tied with 15 knots! Offering you "good luck" from Africa- once the bracelet is firmly in place they demand money!!! Iv not been caught out but just be warned! just walk past ( Well run almost!) and say no thankyou firmly they get the message!!
