There was this one time I had the opportunity to watch a person putting together a fruit platter for a party.
That person used to do that for airline catering and mainly for first class passengers.
I didn't get to see the whole thing but I did learn a bit on how to cut and present pineapple nicely. I got one the other day and tried it myself. Not as nice as I wanted it to look but rather than the usual pineapple rings this is quite appealing too.
