Does anyone go so far as to roast their own beans?
There is a coffee shop in Halifax I used to love to frequent but every Wednesday, they roasted their own beans and I couldn't go anywhere near the place.
The resulting aroma outside is simply awful. Nothing like the addictive smell of the resulting product inside. I won't say what I think it smells like but if you have a hospital nearby that is authorized to incinerate their own 'waste material' (of which I leave the details to your imagination) then you know the smell.
