My place gives you an actual printed receipt, on which the MTCN or whatever its called is on it.
I would never accept just a carbon copy of the form thats sketchy as bullshit, if you go to supermarkets they almost certainty print out a computer print out and you can see what your person wrote. I know this for a fact because one time a dumb bitch put the money not in dollars but some foreign ass currency and I had to call WU to get it straightened out.
