I guess this post is supposed to be rant. It really has nothing to do with race, except for expressing your anger towards one difficult customer.

Take this as lesson but this could very well be any one, nepalese or foreigner. You will soon find out that not every customer is worth your time and effort.

Honestly there is no need to interject race here. Since this seems like new venture, you should learn to accept that you have certain boundaries and you won't let customer walk all over you. That can be both foreign and domestic.

Instead of german lady, replace with any "nationality" and re read your post. You might find it silly.
