Parking scooter in parking lot? Parking disk???

Hello, I would have a rather general question about parking. How do I have to behave if I want to park my 50s scooter (registered on mofa) in a public parking lot? Logically, I am a road user and have to stick to the condition. But how do I solve a parking ticket for my scooter or attach a parking disc? Does this only apply to cars or do they close an eye when they find a scooter for example without a parking disc? I just do it. In addition to the steering wheel lock, a bicycle lock around the scooter and around a permanently installed object (traffic sign ). …Towing can’t be done but what can happen to me? Greeting
