When you pay for a service or when good service is promised, you don't expect anything but the best. But when that's not provided or, even worse, when you experience rudeness from staff then it needs to be pointed out. Writing a letter of complaint to the manager or the person in charge is easy and should definitely be done in this case. Make sure to note why you're upset and what you expect from them as compensation.
