WHACK! I ordered $84 worth of food on Super Bowl Sunday and naturally they were busy.
They had tables set up with all the orders of food.
I gave them my name , was handed my order, and I proceeded to drive to the Super Bowl party 30 mins away, only to find out they ONLY bagged chicken wings in the two big bags. NO FRIES. NO VEGGIES. And worst of all, NO RANCH!!!!
I was heated ofc. 🤬
I called, phone rang for a loooong time, they pick up & immediately hang up.
I called again, they left me on hold for twenty minutes and then hung up.
I called a third time and FINALLY got to speak with the manager which was not pleasant.
To say the least, it was my fault I ordered from this location cuz it’s filthy (I thought I was ordering from the one by Ontario Mills) and I will NEVER make that mistake again.

Ordered my food about 45 minutes before pickup and they were still 15 minutes late on the pick up time despite not being busy.
I will say they did give us extra fries though and ranch and I really appreciated that. I didn’t discover that until we got back home.
The food is usually good from here but the timing is pretty bad
. Then they say it’s going to be “5 minutes” but it’s not.
Not very happy at all. Respecting people’s time is so important

Am I able to submit ideas to Wingstop for future consideration?
We at Wingstop Restaurants Inc. ("Wingstop") are proud that our fans are excited by our brand and want to share their ideas, innovations, flavors, and other wing-loving thoughts with us. However, Wingstop has a full-time staff of wing experts who we rely on to generate new ideas for our brand and our fans. Not that your ideas are unworthy, but you don't want to put the team out of a job. And our lawyers tell us that we need to avoid unsolicited ideas because we don't want to have any dispute as to ownership of those great ideas. Below is more legal mumbo jumbo explaining our policy.
UNSOLICITED IDEAS
Customers of Wingstop may have the perfect idea for a new concept, and we may be missing out on an exciting opportunity, but ownership and protection must be considered. Wingstop maintains a policy that does not permit it or its employees to accept any unsolicited ideas from outside sources (fans and other third parties).
Wingstop strives to innovate and create through internal business departments and their employees. With this in mind, if we create a new concept through our internal experts, and a talented customer/fan submits a substantially similar idea, determining who the originator of the wing-tastic idea is would be a challenge. To better protect ourselves as well as all of our fans out there, we must adhere to this strict policy which does not permit the review, consideration, or acceptance of such ideas from outside parties to avoid any confusion of ownership. Therefore, we encourage you not to send us unsolicited ideas.
TERMS GOVERNING SUBMISSIONS
If you nevertheless insist on sending us your unsolicited ideas, the following conditions apply:
Wingstop shall have no obligations concerning the submissions, including no obligation to review the submissions, return any materials, or acknowledge receipt of the submissions.
All submissions will be deleted from working files within Wingstop and no response will be delivered to confirm receipt of any submissions.
Due to archiving requirements, your email may be retained on our system, but please understand this is not an effort to keep record of our customers' great ideas; rather, it is incidental to archiving.
