This mod does a few things.
First it adds bonus happiness for your settlement to the Armor and Weapon stores which are the only 2 stores that don't provide it.
Second it changes the bonus happiness to all stores to be the same.
And finally happiness is now set to 20, 40 and 60 for Tier 1, Tier 2 and Tier 3 stores respectively.

The highest default happiness was for the Tier 3 Bar which was set at 40. Even at that number it would take dozens of Bars in your settlements to even come close to achieving 100 Happiness. So I decided to give it a little boost and apply that to all stores so all of them were equal.

Compatibility:
No conflicts that I know of unless you have other mods that directly effect happiness values for stores.
Works just fine with any mod that changes the looks of the stores as well.

I hope you enjoy this mod!

• This is a great and fantastic mod that adds several craftable items for your settlements that provide more options for                                                 bonus happiness to help get that 100 happiness level! At least give it a look or check out her other wonderful mods!
  
  

Better Vendor Stalls by kellogsfrostedflakes

• A great mod that adds clutter to the vendor stalls and makes them shorter so they fit into buildings.
