Should me put whiskey in coffee now?!
Sure why not. I'm sure your employer would appreciate that.
It depends. I myself enjoy a little whiskey in coffee, but I also know that the amount of whiskey I've added will not have any affect on me. Now if you're putting more whiskey than coffee, I would have to advise against it.
And then start looking for a new job!
Unless your job is to investigate the outcome of getting drunk at work or to test out new coffee flavours.... then I say No. you not put coffee in whisky to make drunk now. not good idea.
Sounds like you already did.
