MTO needs a big home made Cinnamon Roll - lots of icing and butter - hot from the oven.
I know there's already multiple dipping sauce to go with the cinnapoppers, but non are the traditional white icing or maple icing you get on cinnamon rolls.
For your time.
Sheetz (#347) should have a drink add in/on option for Cinnamon for all MTO drinks. In addition perhaps a shot of expresso should be an option for Milkshakes, there are some great milkshakes that with a shot of expresso taste delicious, at least having the option would be great (as opposed to adding it via another drink and explaining you want it in the milkshake).
