AWA: AA 95 The following appeared as part of an article in the business section of a local newspaper.
“Hippocrene Plumbing Supply recently opened a wholesale outlet in the location once occupied by the Cumquat Cafe. Hippocrene has apparently been quite successful there because it is planning to open a large outlet in a nearby city. But the Cumquat Cafe, one year after moving to its new location, has seen its volume of business drop somewhat from the previous year’s. Clearly, the former site is a better business location, and the Cumquat Cafe has made a mistake in moving to its new address.”
