Just had it happen to me. Taking a photo of a monument, was approached and asked where I came from and said he had a sister who was going to work at the hospital in the city I come from and wants advice for rent, where to live ect.
The vibe just didn’t feel right you could tell, so I made up some bullshit excuse that I was meeting up with my friend who lives here to go get a drink, then they asked what I was doing tomorrow and was pretty persistent. You just know once they are persistent something isn’t right. Sad world we live in that we have to question every person of being genuinely nice because scams like this happen.
