after a hike from tannenboden to the seebenalp (a beautiful hike on the other hand) we bought an ice cream in the restaurant to enjoy it on the lake. Although no one else was there, the staff worked very stressed and became really impatient as someone of us didn't know exactly what kind of ice she would like.On the way back we bought another coffee. I felt more of a disturbing factor than a customer. we also had a few empty pet bottles and a little bit of a mum from the walk; when we asked if we could still dispose of it, the answer was casual: "so we have to pay for it too." so no. to ask where the next public mülleimer would be just a "I don't know." Although we found this then after 15 minutes for a walk back to tanneboden.I think that the restaurant can still improve in matters more easily. if we had only felt a bit welcome, then the mumbling would have been with the drink money that we would have been given loosely.
