I have found, can be most helpful.
One day while shopping I struggled to find something, I asked a lady and she took me to the right aisle and explained the difference in the products so I knew which one to buy,
another time I was paying for something and didn't have my credit card, they wouldn't accept cash, a lovely Qatari man paid with his card and let me give him the cash.
Just a couple of examples but good ones I think :) x
