Yes, I do sometimes at work as we have no taps in the shop and therefore cannot wash up cups.
However, I have become more aware of these due to them being in the news and I no longer ask for a take away cup in a coffee lounge.
I used to do this as I found it stayed hotter in one of these cups than a ceramic or china cup.
I would have thought someone would come up with a cup that is bio degradable by now!
I try not to use them. If I don't have my mug with me I will go without a coffee when out, if take away cups are the only choice.
I regularly donate blood / plasma and stay for a cuppa after. Recently the Blood Bank changed to take away cups and I have been caught short twice. I shall try to be sure to bring my mug in future. I bought the cup home , the first time, to use in my studio to rinse brushes or whatever but it is not ideal.
I worry so much for the health of our poor planet if we keep acting carelessly.
We've always used ordinary coffee mugs at home, & I use to reclye the above ones when I drank out, but not so long ago, I was informed about the WAX they use on the old side of the paper, so they can't be recycled! Not very helpful to the environment I won't have thought.
Very rarely, I take a stainless steel mug with a lid that I bought for seven dollars at Kmart, similar to the Thermos ones but much cheaper and just as good, Keeps the liquid hot much longer and of course totally reusable and washable etc, and planet friendly! With all the hullabaloo on tv these days about throw away cups why are the cafe still using them and the population not avoiding them! Some cafes give me a discount for bringing my own cup woo hoo...
Sadly I do still use take away cups a fair bit. Well...less than I used when I worked everyday in the city, but I still get about one per week when I do my shopping. I do try to cut back where I can and my goal this year is to start taking my own travel mug.
