Celestia is sick and tired of having mediocre cups of coffee in Canterlot. The coffee chains they have in the city are a bust, and none of the ponies seem to know how to make anything other than basic, plain old coffee! Maybe she needs to scout out a better franchise and better hired help in order to get a decent cup of joe for a change. Maybe she even needs to search outside of the pony realm to do it.
WARNING: Contains human to pony transformation, stressful situations, brainwashing, and overly complicated sweet girly coffee abominations.
