No Tip... Sorry

[WhatThe]

I still say this is a hoax. The hand writing doesn't match IMO.

#2 You have no idea the circumstances this person is in. It could be that this was a special event and she saved for it.
She could have done without other things to come up with her $140 budget for a special family outing.
#3 Posting the bill is most likely illegal since it displays her signature. That signature is a part of the contract between the
customer, the restaurant, and the credit card company.

2 very good points I hadn't thought of.

Clearly, more information is required about the circumstances of this transaction in order to understand anything.

Paying the bill and leaving no tip is better than doing a "dine and dash".

The employee that posted this receipt to the internet is the only person guilty of any wrong doing here and is lacking in the morals department.
