Like many millions of people Mr. Shallots and I drink soft drinks, water and iced tea every day, at least three times, if not more. So our glass ware does get broken.
I like certain dimensions in water and iced tea glasses and I want a certain minimum strength of glass. I like them clear so I can check that they are clean.
So, when I go searching for glassware, the world wants to sell me beer steins, 40 gazillion different wine glasses and twentytwo thousand styles of coffee and hot tea cups/mugs/etc.
Maybe someone will realize that there's also a market out there for classic glasswear for water and water's kin.
