Stop in for a cup of coffee

I got an email from work tonight with a letter attached saying they are finally paying my bonus for last year that is 2 months overdue. It is equal to 20% of my salary so it it is a sizable chunk of money.

I don't know if they paid everyone or just me, but I have been squawking about it for the past few weeks saying if it doesn’t come soon, I walk. The letter was signed by someone who wouldn’t normally sign it, so IDK.
