Keep letting them buy you coffee. Once you have cup #100 you get superspeed and can save everyone in case there is a fire.

Or just be honest and say I've already had coffee but your offer is very kind thank you

That much coffee in that short amount of time, sounds like a normal day, for me anyway. I do love coffee!

Having too much is dangerous and it is not impolite to say no. It is an offer - they won't be offended eitherway.

voulez-vous un autre tassè du cafe? ;P

i wish someone would buy me coffee!

Oh wow. You should just keep a coffee cup on your desk so when someone else offers, just lift up the cup and say thanks but you already have one. Then you're still being polite,but you have a valid excuse to not accept the coffee.

You're too sweet.

next thing you know, "wanna head to my place?".

Be careful with all that coffee/caffeine! It will sky rocket your heart rate! At least ask for decaf

you need to say no soon, a friends of mines father, drank 5 pots of coffee every day, after a while, he developed a serious issue with his... lets just say.. sometimes he needs a toilet very badly and it's not #1, when you've seen a grown man run into the forrest (group of trees really) while on a walk and wondered why when he came back, you learn from such an observation. just say, very kind of you, but i just had some a moment ago or something similar, they will understand if they are heavy coffee drinkers themselves. good luck

Just say No Thankyou...
