Giving a Tims or Starbucks card as a Thank You to secretaries or school staff is a good idea. It is also a good idea to purchase coffees and fixings for the Main Office. However, knowing exactly what each person takes in their coffee and bringing it to them is better as it is a recognition of the individual. It is the same as a handwritten note that is personalized.
Bow Valley High School created a database of what each staff member liked as their hot drink of choice and what was included in it. From tea to Tim’s was entered into the database, so students knew what to take to the teacher’s room the first class the next morning after they have chaperoned an event.
You know that things will go wrong and it is a good idea to have your custodial or support staff on your side before things go wrong. Buying coffee for them on a semi-regular “just because” basis is better than buying a “thank you” coffee after they have rescued you from a mess. You are filling up the emotional bank account before you have to draw on it.
