When I want to mail something back to the States, I walk into Tropic air and look for an over 50 yr old USA person... I never miss knowing who is from the USA. They just look, talk I don't know they just are??? So, any way I flash them a smile and ask if they are going back to the US today. If they are and you can tell that too... I ask them if they would mail this envelope for me. They usually say sure and that is that - if they look puzzled I say "I never know how long it will take if I mail it from here" or something along those lines. This has worked repeatedly for me.
See you at the pool??? Pam
