The restaurant was nice. The company was great. The food was fantastic. And the wine was ... well, a bit skimpy on the pour.
Or at least that's the way it looked in the large goblet in which it was served. In a more modestly-sized glass it would have seemed normal or perhaps even generous.
But because of the stemware I spent the first minute or two not thinking about the taste of the wine, but instead about the size of the pour in relation to the price per glass, not exactly where I wanted my brain to be working.
Whatever your product or service, you might want to think about price and portion to make sure you are maximizing your sales and profits while preserving high customer satisfaction. You want people enjoying the actual product not thinking about price and value.
