It brings a whole new meaning to “drive-thru” service, but a downtown restaurant manager was shocked to see a Canada Post truck plow through his business’s window yesterday morning.

Gord Grant said there were about a dozen patrons dining in the Fourth and 4th Restaurant & Pub around 10 a.m. when the truck driven by a woman, who Grant said appeared to be in her 40s, careened through the window where six patrons were sitting.

“It was very lucky nobody was seriously hurt,” Grant said, adding a man sitting closest to the window was sent to hospital with minor injuries. “I was actually surprised by how calm everybody was when it happened.”

Calgary police Insp. Rob Williams said police weren’t called to the scene and doubted charges would be laid.

“It’s a very unfortunate incident and Canada Post is extremely concerned anytime something like this happens,” said spokesperson Sandra Sobko, adding they are fully co-operating with any investigation.
