user3149: I'm wondering if a student can disappoint their chess coach if they lose to many games for a long duration of time or any other reasons. What have been your experience as a student or teacher?

user12540: I am not a Chess Coach though but surely a coach will get disappointed if the student commits the same mistake over a period of time, and does not show discipline enough to improve his weaknesses. 
A coach will get disappointed if a student is unworthy to take any lessons and does not show interest in chess. 
A coach may get disappointed if a brilliant student is unable to pay his fees on time. 
As students are a reflection of their teacher's training, and learning, a coach will want his students to shine so that his name also shines along with them.
There can be other different cases but the above ones are most common.

user12449: I, as a teacher of elementary age students, don't get disappointed in the students' results.  I only get disappointed if the student doesn't try.
