its like spreading the love!! I tip everyone i can, and we all should. I tip the guys who pack my bags about ten qr once a week, tip the guys who put petrol in my car like 5 - 10 qr, never had anyone push a trolley for me thou - thats what my arms are for!

tip in resturants too,thou not fast food outlets for some reason ( does anyone tip there ?)

we should all tip those who can afford to, people earn very little out here and no matter who you think you are that could be you one day, so treat everyone as if you know them when you are dealing with them in these situations! And always say please and thank you too, you would be amazed how few do!
