Too old-fashioned to use porcelain and glassware?

Serving food and drink in porcelain or glassware was a natural thing to do. They are durable (if you don't break them), do not release poison under high heat, and are washable - so that you can keep reusing them until you break, or chip them. But since when have we discarded that practice and opted for non-reusable tableware?

I guess I can accept someone arguing that they ‘need’ a non-reusable plastic cup for their takeaway drinks, but to serve drinks in that to a dine-in customer? Beats me.

Can someone tell me the point of that, please? Here in Singapore, I am sitting at a table in a restaurant, stationary. Yet, when my drink came, it was in a disposable plastic cup, complete with sealed cover, and a straw strike through it.

They must have heard me wrongly, and thought that I wanted it to go. So I asked them.

They said: No, it’s not a mistake. That’s how we serve drinks here.
But I am sitting down, not walking around or jumping around with the drink in my hand. Why do I need it sealed, plus a straw?
That’s how we serve drinks here.
But I don’t even need a straw. I can drink from the cup. I’m way passed the sippy-cup training stage.
That’s how we serve drinks here.
Can I request for my drinks to be served in normal cups?
That’s how we serve drinks here.

WRONG. The right answer is: "we are too bloody lazy that we can’t be bothered to do ‘unnecessary’ washing up. Traditional reusable tableware is too much a hassle, and doesn't solve our lazy problem. And we do not welcome freaks like you."

I now check with the food outlet’s serving method before I commit to any purchase. Yes I may be an unwelcome freak, but I managed to slow down the process of adding on more unnecessary waste to landfill, slowly but surely.
