DETROIT — Eleven

patrons ditched out on a nearly $120 bill last Sunday, according Juan, a manager at the restaurant who declined to provide his last name.

He said several members of the group — comprised of men, women and children — were angry that the restaurant added a 15 percent gratuity, which is the policy for parties of eight or more at Mi Pueblo.

The Mexican eatery located at 7278 Dix in southwest Detroit isn't letting the expensive and underhanded move be forgotten.

Instead, they're going to social media.

Someone has even used the picture to create "meme,"

The photo was edited with the addition of text. At the top of the image it says, "I usually don't go out to eat," and at the bottom, "But when I do, I don't pay."

Juan said the woman in the photo contested the automatic 15 percent gratuity and when she couldn't resolve the matter with staff, asked to speak to the manager.

When the manager and employee returned, the entire group had left, said Juan.

This is the explanation on the Mi Pueblo Facebook page, which Juan said is managed by a third party:

Juan said he wasn't sure, but believes the gratuity policy is printed on the menu.

Wait staff "are paid by hour but let's say the largest percentage of their salary is mostly tips," said Juan.

He said policy at the restaurant requires the wait staff pay 50 percent of any bill patrons skip out on, because "it's part of your job to collect the money from the customers."

"In this case, I think the owner made an exception," Juan said.
