There was a toast bar around the corner from our office. Bread supplied by a bakery two blocks down.<p>It was frikkin delicious. Swedish toast, with some nordic cheese and jam. Garlic cream cheese with fresh cherry tomatoes. Avocado.<p>But it doesn&#x27;t scale. The long queue and wait time deterred customers, with the over flow going to other cafes.<p>The owners tried all sorts of gear to make toast reliably, consistently, and faster rate. (I have no idea why that&#x27;s a hard problem.) They finally ran out of energy (will to live) and closed shop.
