Something that would be a great dynamic on your “rise to the top”, is how you interact with the competition. Right now you can try to make your place more appealing (cleanliness, customer service, variety), but it would be interesting to have the negative option for your competition as well.
For instance: You could advertise to draw people to your store. You could also do a smear campaign to drive them away from your top competitor.
You could sabotage your competitor’s supply line, and you could hire security to guard your own.
But while doing these things might draw the customers to you, it could make businesses wary of doing deals with you, etc.
I know this idea involves a lot of undeveloped concepts, so it may not work with current plans, but I figured I’d throw the idea out!
