Why do you think deer associate coffee with people? Deer don't give a crap about the smell of coffee. It might attract them. Human scent is the only scent that I have ever seen spook a deer. And if the deer is downwind of you so that it can smell your coffee, it has already smelled you, too.I dont drink coffee, but even I can smell it from a looooong ways off. Sure deer can too, and relate smell to humans.
