I find Tim Hortons coffee too hot to hold especially while drinking and driving. Yes, I drink coffee and drive. It’s not against the law. 
When I make my coffee order at Tim Horton’s drive thru in the morning I would ask for ‘Double Cup’. The optimum brewing temperature of coffee is 90′c which is pretty much close to boiling. This is too hot for me to hold.
I often wondered why Tim Horton’s doesn’t have coffee sleeves. Today I think I figured out why.
IT’S NOT COST EFFECTIVE. It’s better to employ double cup. Take a look at this price chart at a restaurant supplies store.
Look at the price of Coffee sleeves. It’s is $37.99 for a box of 1000s. Take a look at the price of 1000s cups. It around the same price! Therefore, if Tim Hortons have coffee sleeves in the store probably about 25%* of the patrons would use it. Currently, probably about 5% of the patrons would ask for Double Cup. Hence, it’s better to not use sleeves and let the customers ask for Double Cup.
*number is educated guess. When I worked at Starbucks, 95% of patrons use coffee sleeves. 25% is a low end guess.
