There are many people that advise that a food truck owners should give difficult feedback immediately, preferably within 24 hours of an incident. But next time you have to provide constructive criticism to one of your food truck staff members, consider sleeping on it first.
Your input will be far more effective, and better received, if you aren’t feeling agitated. Of course there will be items that need immediate discussion, but if the feedback doesn’t revolve around employee or customer safety put some distance between the offending action and the feedback to gain perspective. You may need to calm down over several days. This will give you time to prepare, consider the other’s point of view, and deliver the message in a calm and helpful way.
