"..I asked:where is the helper? I want to take this things to any bag. i cant do it alone.."
...do you mean, you cannot put "some vegetables" into bags?? Are you disabled? don't have hands? are there helpers in your country? In my country everyone helps him/herself, we dont have slaves.

Goodness, what a pity man, who cannot put few veggies into bags..

Besides, you go to the cheapest shop in Doha, and you also expect some good service. In order to get a good service one has to PAY well.
