If you are a brick and mortar business, cleanliness is important to many customers. I am a bathroom person, so it disgusts me to go to a restroom that is nasty. I realize that the people using it are the ones usually making it that way, BUT that does not reflect on them as much as the business itself. Water slung everywhere, paper on the floors, mirrors covered in water spots and toilets needing to be flushed are poor reflections of your business. Take the time to check these areas out during the day. If you are a large business, you may have employees doing checks. Make sure they are actually doing clean up because I go into many stores and see employee sign offs, but they are so nasty that nothing has been done.
Another area for larger stores with carts is to keep the carts near the door. Send someone out to bring carts back. The carts need to be cleaned out also. My husband shops at some of the larger stores for household and yard items on a regular basis. He could not find a cart in the store on a beautiful spring day on a weekend. This is when everyone is buying. He actually had an employee tell him that they were all in the parking lot and he could find one there. Most of the carts there have paper and trash in them most of the time. NO CART TO CARRY ITEMS, THEN NO SALES.
