I have lived in Thailand for many years. Thais think farangs pockets are lined with Gold.
I have now come to Vietnam to live permanently Its still the same but more blatant.
When I go shopping I pay more for every item.
Example
Small milk drinks I pay 30000 Vnd Wife pays 24000 Vnd
Vietnamese Rum " " 100000 Vnd Wife pays 75000 Vnd
Crisps I pay 10000 Vnd Wife pays 6000 Vnd
So my Wife has to do all the shopping.Or I go with her to show the shop keepers that we are together and not to rip me off!
