How does the math work in this riddle?

Three guys go to the bar and get £30 worth of drinks. They pay £10 (10*3=30) each and the waitress takes the money. Before she puts it in the till the manager notices the guys and tells her “I know these guys, give them a £5 discount”
On the way to their table the waitress decides to give the guys £3 back and keep £2 as a tip.
The guys take a pound each, so instead of paying £10 each they end up paying £9 each (9*3=27).

And the question is: if they ended up paying £27 and the waitress kept £2 where did the last pound go?

You start with $30 of beer, $30 for payment and $0 of change.

Then the manager changed it to $25 of beer. There’s still $30 in payment, with n $5 in change.

The waitress takes her tip. Now you have $25 of beer, $30 payment, $2 tip, and $3 change.

The whole riddle is basically just adding things wrong to confuse the reader.
