How does this even happen?
Does the daily grind of heavily typed status updates wear down the table legs? Do furniture stores sell slightly uneven tables at a deep discount? Is someone going around with a tiny razor and shaving off little bits of table just to be a dick?
I just don't get it. I built a table once, and I did a pretty crappy job, but it doesn't shake. If I can get the probably-stoned Home Depot guy to cut a set of even 4x4s, then successfully nail them together myself, a mass-manufactured table shouldn't be so shoddy that coffee spills all over my notebook.
Why does no one fix them?
It's really hard to start a coffee shop, but it isn't hard to tape a small piece of paper to a table leg. Pulling a proper shot of espresso takes great precision, balancing a table does not. At the end of every shift when the barista wipes down the table, how do they not notice that it rocks like the deck of a cruise ship?
