I have often lent 500baht or so to Thai relatives knowing i will probably never get it back
The good thing is they never ask again.
You get relatives asking to borrow 10,000 baht but no chance with that.
Got someone borrow 2500baht once and never seen that again ,worse part is they kept saying they had no money but you see them with beer or get a new honda wave which annoys the fu7k out of me
