The “TellTims Survey” refers to a customer feedback survey for Tim Hortons, a popular Canadian-based chain of coffee shops that has locations in multiple countries. Customers who visit Tim Hortons are often provided with an opportunity, typically through a receipt, to participate in this survey to provide feedback about their visit. In return for their feedback, they might receive a reward, discount, or entry into a sweepstakes, depending on the current promotion. If you’re considering participating, follow the instructions on your receipt, and ensure you have a recent visit to reference. Always be sure to provide honest feedback to help the company improve its services.
