The Lincoln ME Wendys is very slow and very unprofessional…the food has been cold when I received it,

The service is very very slow, unprofessional and Ive had cold food and undercooked food. Also the workers are always complaining about working short, now I have a grandson who “works” there but he cant seem to get any hours! He may get 6-8 in one shift once day a week! He has told the scheduler that he needs more hours but then he’ll go one to two weeks with NO hours! I dont understand how the manager(s) are not seeing this and why they are not doing anything about it, Wendys in Lincoln ME needs to do better if they are going to make a successful business in town
