Something like 2 years ago, a guy in my class sent me this pic, he told me, "doesn't it remind u this morning course?" lollll.The worse is that it did loll, the coffee machine of the school was out of order, and we had a boring course, everybody was sleepin in class! We're gonona be the futur businessmen and women....for the 30 next years at least :)))
So I advice every company to propose coffee for free if you look for efficiency!
