Terrible expensive studio photo session – Is it true ?

Today i get a phone call from one lady, she asked how much cost studio glamour photo session. I said that the cost is 100 euro only. And for that 100 euro she will get:
full photo session, cd with all professional processed photos and 6 printouts (A4 formatt)
Than she said:
“Ohh my God , why is so expensive” and angry hung out the connection.
I was very surprised from her reaction.
Now my friends lets see how expensive is photo session in our studio:
The cost as I said is 100 euro
time for photo session 3 hours
time for selection best shots 1 hour
time for post processing per one photo is about 1 hour (and usually is at least 10 photos) so lets say 10 h
time for printing preparation is about 2 hours
time for printing for 10 photos is about 2 hours
time CD recording is about half hour (i will not add this to total)
So total time per one photo session for photographer is 18 hours
so simply calulatio 100 euro devided by 18 hours will give us 5.56 euro per hour
than add electricity power usage, my equipment usage etc
Now dear LADY let say again than I am expensive !!!!
(btw what is the minimum wages per hour in IRL ) ???
