When it comes to ice cream chains, there are very few companies that are as popular as Dairy Queen. That is why more and more people are going to the chain as much as possible, especially during the summer months. Those people who are willing to do the DQ fan survey are eligible to win a few prizes as well.
There are a lot of different companies that offer surveys of some kind so that they can get feedback from customers. This feedback can help make everything a little bit easier for them in general. Maybe they will use some of that feedback for future plans, or they just want to see what is testing well.
If a person is a fan of the restaurant, they should definitely fill out the survey. This is the best way to give them the information they need back.
