Amy somehow manages to fall short of $40 all three days at first, losing

Amy did her best to be the most charming, endearing and likeable waitress, yet despite her best efforts, none of the customers seemed willing to tip her all that much, at best, she got a dollar from every order she fulfilled, regardless of how much the order was.

15% of two cups of regular sized coffees was about a single dollar, and she never got any more than $1.50 as a tip from any order, even large, 4 grand sized cups that should have gained her anywhere near 3 to 4 dollars.

And it wasn't that the customers were especially cheap that day, she noticed all the other waitresses and waiters were getting much more in tips than her.

that meant that by the end of the first three days, Amy could barely break the $30 barrier; and each day Samantha would come by and make sure she was removing all the clothes she had to.

It was an easy choice at first, her shoes and socks, nobody really noticed the barefoot waitress on the third day, but on the start of the fourth day, Amy had to pick her piece carefully.
