In real life holding is about as common as being hit by lightening.
Even when you do get a hold its usually just a vectored hold, not a
formal procedures. The only time you really get to fly holds is to
remote airports without ATC when the approach procedure requires a hold
for the procedure turn.

I've read that holds have become very rare since ATC adopted the
policy of spacing flights from their departure points rather than en
route. I remember when I was young hearing about holding patterns a
lot, but apparently those are largely a thing of the past.
