When I was a student in france I ' m french , I use to work in a library , in the scolar area . People came and said to me I want the blue math book . I said Hello , and freeze myself until they get it . It worked most of the time . And if they didn ' t get I would act like a dumb person asking them what color is the book and if it was a french or a biology book but 15 times . I litterally won the book selling thing . <| sep |> So by that logic , you don ' t believe people should drink coffee at work . caffeine is a drug , it changes you when you use it . Weed , especially with experienced users , is like a second reality for some people . It is more enjoyable , interesting , and can be generally better than people ' s sober reality , but they are still able to function totally fine .
