Well, it works if you're a woman, according to a study in this report (click here) in the British Mail newspaper.
Here's an excerpt:
Waitresses who wear red get up to 26 per cent extra in tips than they would wearing other colours, researchers claimed today.
However, the team that the sexes tip very differently - with the bigger tips coming only from male customers.
No matter what colour they wear, female diners will give the same kind of amounts for service every time. Yet men, whether they realise it or not, add anything between 15 and 26 per cent more to a waitress in red than they would if it was the SAME waitress wearing a different colour.
The test was simple. Take 11 waitresses in five restaurants over a six week period and ask them to wear the same kind of tee-shirt every day but alternate the colours.
We should test that theory out, shouldn't we?
