A food delivery driver in California found a way to shake up one of his clients -- by slurping from a milkshake he was supposed to deliver. Homeowner Rajesh Malhotra didn't see the incident unfold in real time, but when his son went back to review footage from his doorbell camera later, the pair caught every drop. 14-year-old Rishab Malhotra said he watched the driver slurp the shake through a straw before tossing the straw aside, adding, "Once I checked it out, I brushed five, six times. I felt really disgusted!" Doordash didn't return calls from the family, and hasn't said if the driver has been disciplined. (KTXL-TV)
