OK, here's the easy solution.
The men were charged $30, when the should have only been charged $25. They SHOULD HAVE received a $5 refund. But they didn't, they received $3 back (meaning they each paid only $9). The hotel kept the $2 making the actualy price of the room $27 not $25.
No...the easy solution is all of them saying make the beast with two backs it and going to the strip club.
