Since many years I use nothing but double wall vacuum insulated glasses, cups and containers, I love how they keep things hot or cold forever. I remember having my mind boggled at how the ice in my drink hadn't melted over 24 hours later including having spent hours in the sun where the bottle was almost too hot to touch on the outside yet the next day the ice that was left in my drink still hadn't melted.

These are the ones I use the most:
-2oz glass cup for espresso
-12oz glass mug for coffee
-20oz and 30oz stainless steel tumblers for cold drinks
-24oz, 30oz and 50oz stainless steel bottles for cold drinks on the go
-12oz and 28oz stainless steel food containers for keeping food hot or cold on the go

I use the bottles and food containers on motorcycle rides, on hot days I bring both my 24 and 50oz bottles so I can stay hydrated all day and sometimes bring my 12 or 28oz food containers to bring something to eat if I want to avoid eating at a restaurant.

I think they all paid for themselves by preventing me from buying cold drinks at a convenience store or ordering from a restaurant, and they can be expensive, some of them have been as much as around $50 US like the 28oz food container but even it was probably paid after 5-10 uses compared to ordering at a restaurant.

no i don't

i have never been a bring a soup to work person or care if there's ice in my drink

i don't really even eat at work. i bring a RTD protein shake and sometimes maybe a banana
