Missing Dollar-Celticpiney26

The ending of the riddle is misleading. While the riddle is trying to make you multiply 9 by 3 and then add the two dollars in the waiters pocket which would only add up to 29 the real answer is that all the money is all there. There is $25 in the register from the corrected bill, there is $2 in the waiters pocket, and each of the three ladies is given a dollar each which adds up to $30 in total. 25+2+1+1+1=30
