If one and a half hens lay one and a half eggs in one and a half days, how many eggs does one hen lay in one day? Two friends have a nice meal together, and the bill is $25

The friends pay $15 each, which the Waiter gives to the Cashier

The Cashier hands back $5 to the Waiter

The Waiter keeps $3 as a tip and hands back $1 each

So, the friends paid $14 each for the meal, for a total of $28. The Waiter has $3, and that makes $31. Where did the other dollar come from?
