The "smart" beer mat
Beer mat knows when it is refill timeA coaster that can sense when a glass is nearly empty, sending an alert to a central computer behind the bar so waiters know there are thirsty customers.
I saw this a few days ago, and in
theory it's a great idea. However, think about the
last time you were out drinking. How often did you
leave your beer on a coaster? When was the
last time you ordered beer that was on tap?
As long as you constantly put your beer back on the
coaster, this would work wonders. As long as the bar
staff had been properly trained. Otherwise, they
could just ingore your beer mat as easily as they
previously ignored you!
But still a really cool idea. Now if the people who
come up with stuff like this could use their powers
for good and come up with a cure for cancer!
