Customers at a northwest Tim Hortons restaurant were treated to a free cup of coffee after an anonymous man bought 500 cups for customers.

The Tim Hortons in Crowfoot Crossing is the second store in Alberta this week to give out the courtesy coffees.

On Monday, a man walked into a store in downtown Edmonton and ordered a large double-double and doughnut and then proceeded to purchase $859 worth of coffee to pay it forward to other connoisseurs.

He told the manager 'you have to give it to the next 500 customers’ and then quickly left the store.

Staff at the Crowfoot restaurant say a man walked in about 11:00 a.m. Wednesday and ordered 500 medium coffees.

“I was blown away,” said Kelli, Manager of the Crowfoot Tim Hortons. “The random act of kindness that he did today, just amazing, you don’t see that.”

Kelli says the staff members were thrilled to be able to tell customers that their coffee was free.

“There are 500 customers that come in and want coffee, won’t have to pay for it today,” said Kelli. “His reasoning was that Calgary has been through so much with the floods and everything he just wants to be able to lift the spirits and hopes to make people’s day a little bit brighter and a little bit better.

The same man is not responsible for the Edmonton give away but he says he did see coverage of the Edmonton man’s gesture and decided to do the same.

Staff at the restaurant say the man is known to them and comes into the store once in a while but they don’t know his name.

The total cost of the courtesy coffees was just under $900 and so far they have handed out about 65 percent of them.

It took the Edmonton store almost 24 hours to hand out all the coffee to its customers.
