Every Friday, Lynda Steele dips into the viewer mailbag to answer your questions. This week, Steele on Your Side investigates complaints of an undercooked burger at McDonald’s and an app to “out” motorists who park in stalls reserved for people with disabilities.

Undercooked burger

Cheryl emailed CTV News after an alarming incident at a Vancouver McDonald's. She had ordered a burger at the drive through of the Main and Terminal McDonald's but was shocked when she took a bite into her burger.

When she opened the burger she said she was horrified to see what appeared to be a red and undercooked meat.

She says she attempted to contact McDonald’s and when she didn’t hear back she contacted Steele on Your Side.

When reached for comment, McDonald's said that once the restaurant heard about the complaint it immediately stopped production of the grills, and checked the temperatures and settings on the equipment.

"As there were no other incidents or reported issues, no product testing issues and no equipment or procedural issues; we believe this to be an isolated incident that may have been caused by human error,” the company said in an email.

McDonald's said it regrets the occurrence and apologizes to Cheryl for the incident.

Parking mobility app

Several viewers contacted CTV News following the story about misuse of disabled parking stalls.

If you would like to "out" a motorist who's using one of these parking stalls without a permit, there's a Made-in-Vancouver app for that.

It's free and it's called Parking Mobility.  When you see a vehicle parked illegally, just snap three photos, one of the license plate, one of the front window and one showing the vehicle and the disabled sign and press submit.

The app then contacts the city, which tickets the vehicle's owner.
