A bar girl delivers 3 meals to 3 people at the bar.....they add up to £30, so they each give her £10, and no tip.....she then takes the £30 to her boss......her boss then say's he's made a mistake and it should only have cost £25, so he gives the bar girl £5 and tells her to take it back to the 3 people. She decides to only give them a pound each, and keep £2 as a tip.
So it works out they ended up paying £9 each for the meal.....3 x 9 = 27
That leaves £3.....yet the bar girl only kept a £2 tip?.....what happened to the other pound?
