A pizza deliverer in central Florida has been charged with pushing her way into a motel room with an accomplice and stabbing a pregnant woman after a dispute over a tip, authorities said. Brianna Alvelo was charged with stabbing a woman in her motel room in Kissimmee, Florida, a short time after delivering a pizza to her on Sunday, according to the Osceola County Sheriff's Office. The woman gave Alvelo $50 on a $33.10 bill, expecting change back. When Alvelo started walking away, the woman asked for money back, and the pizza deliverer told her they didn't make change as a policy, according to an arrest report. The woman began searching for smaller denominations in two purses in her motel room and in her car, with Alvelo watching. She got a smaller dollar bill from her boyfriend, with whom she was staying at the hotel along with her 5-year-old daughter, and Alvelo's tip ended up being $2, the report said.
