A little more team work
I would communicate well with the team members.
Start with what you do great and build off that foundation.
Higher the correct people and mentor them to provide top service and win those customers over. There not bad customers these are your bread and butter.
Win them over. You need them to come back and tell all their friends.
I would want to have all employees be responsible for cleaning up for themselves, instead of leaving all the cleaning for the sales staff.
