I have coasters but they aren't out all the time. I just have a stack in the kitchen. If I serve someone a drink, I put it on a coaster when I set it before them on the coffee table and HOPE they use it.
I had that exact little drawer style set, way back in the 70's...
Today I still use coasters in fact this week I bought some new ones.. I have some fun ones that I use here in the office which are these little 45 record label copies which I've used here for about 2 years..... they're so fun...
...and this week I got some Plain silicone ones for downstairs...
Years ago, when some company I was dealing with often sent out all kinds of freebies, I received a set of 4 coasters- rubbery material with designs (see image)..
A maintenance guy came in, noticed them, and asked 'Are they RECORDS?' He didn't know what records were- or coasters either!!
