I can see where Wings is coming from. But I don't think it would annoy me if people thought I was a tourist. I would simply correct them of their error. To be honest, I can't be bothered reading through sh**loads of text to get every small point, but if you are unhappy with any assumptions made because of colour, creed etc., just calmly correct the person. If you get a tourist discount when you don't comply to regulations of it, you've got 2 choices. Either take it, break the law, & never visit the shop again, or be honest & correct the shop worker of his error
