Tim Hortons review: serving size

I ordered a Medium sugar free vanilla cappuccino at the drive thru window of the Tim Horton's at 891 North State Street, WESTERVILLE, OH, 44082, USA.

The amount of beverage was not the amount I paid for. In fact, the cappuccino was fully 3 inches BELOW the lid and the minimum mark indicated on the cup.

Since this type of issue seems to be a continuing problem at several WESTERVILLE, OH Tim Horton's stores, request you address the issue to determine what the cause is.

Merci, thank you.

Kind regards,
Patricia Lumbert
