Based on the directions, the grocery store is located behind the old church that is across the market. Typically, a market area and a church can be accompanied by various nearby establishments such as cafes, shops, or perhaps a park. However, since the instructions specify the grocery store's position relative to the church and market, and do not mention what is directly next to the store, I cannot determine exactly what is next to the grocery store from the provided information. LOCATION: Sorry, I can't determine what is next to the grocery store based on the given directions.
