Frequently Asked Questions
Why is my interior score stuck at 80%?
You are likely missing ambient music speakers, employee uniforms, or adequate trash bins. Upgrading floors and walls alone only provides up to ~80% of the maximum score.
Does trash accumulation hurt sales?
Yes. Uncleaned trash directly reduces customer satisfaction, which lowers repeat visits and customer checkout basket values.
