I'd consider anything beyond what's expected of them to considered expected / acceptable service. Unfortunately, the guidelines aren't explicitly clear on what Five Guys expects on their employees other than:
-Cashier greeting, upselling, accurately taking your order, etc.
-Crew members keeping a clean kitchen, wearing gloves shaking their fries, etc.
-Crew members maintaining the dining area and stocking the drink and condiment station.
Basically the simple things you'd expect from a fast food / fast casual restaurant.
What about table visits from the employees asking customers how their meals are going?
What about employees going out of their way automatically for customers that need a high-chair for their children?
Things like this I'd consider going beyond what's expected for a restaurant like this.
Very infrequently shopping the Greater Denver Area, Colorado Springs and in-between in Colorado these days.
