I can only agree with Kijado's thread of the same name a year ago, I had the same experience (Affoltern a.A.). Quote: "It annoys me that every time I return spray cans to customer service I have to explain myself somehow or get a dirty look. Couldn't you train the customer service to take back the cans simply and nicely, or otherwise make a compartment in the returns wall for this? I also only return the spray cans that I bought in Migros, but that also seems to be difficult/ a problem somehow. I thought that was the way to go, but if the return goes straight into the trash anyway, I can dispose of them directly in my trash, no problem."
