Made an appointment(Delran, NJ) for full grooming. The day before received call asking if dog could arrive one hour earlier. Advised Pet Smart worker that attempt would be made to leave work earlier. However, I still needed travel time to return to area, pick up dog and drive to appointment. Response, it should be fine when you arrive. Appointment changed from 3:00pm to 2:00pm and we arrived in the store at 2:05pm the next day. Waited outside grooming space for another customer to come out of check in area due to COVID requirements. Walked in with dog after pet owner completed check in and was told my scheduled grooming appointment couldn't be completed due to a tight schedule.Time was 2:15pm when other pet owner exited check in. So, my early leave from work, drive, pick up and arrival were a waste of time!!! Spoke to manager, but she gave no support or alternative. As a result, other grooming alternatives are underway and going forward my pet will groomed, but not with Pet Smart. Poor service and leadership displayed and experienced!
