...its an easy way of getting rid of the 2's, 5's and ten's
i've learnt it's rude to leave your small coins like 1's, 2's, 5's!
In DC-10 on Monday I bought a bottle of beer for 7 euros, gave the girl a 10 euro note . When I lifted the 3 euro off the tip dish she looked at me in disgust and banged the dish off the counter a few times.
No tip for her.
