Sheriff's deputies are on the lookout for a pregnant woman who went berserk at a McDonald's in Florida.

The suspect allegedly became enraged when her drive-thru order was taking too long on Thursday in Lakeland.

Employees say she stormed in the restaurant and went behind the counter and started throwing bottles and cups.

The Polk County Sheriff's Office was surprised that she actually called 911 to complain about her service.

Before leaving the McDonald's, the suspect lifted up her shirt and exposed her belly at the employees and began twerking at them.

Once deputies get jones in custody, she'll face charges for burglary with assault, criminal mischief and disorderly conduct.
