Context: So , I had a flight in business last friday GVA - ZUR - PRG , and the ZUR - PRG left of the trip was really great ! ( yesterday 's flight in economy was a little less so due to someone next to me nearly having a fight with the kids on front that kept banging around in their seats ... but you ca n't have everything ) . I wo n't mention names as moderators typically seem to remove them from this forum , but a certain male FA in business , provided an absolutely stellar service , filled my cup multiple times with Champagne ( never did I even need to ask for more ) and overall , he was very attentive to our needs and always with a smile .
Question: What may be the reason I wrote this ?
Options: 
A. To complain about my experience .
B. To review my flight .
C. To warn others .
D. To compare flights .
