At first thought, I think that he had the best intentions at heart and he shouldn't have refused you cake. For all he knows it was your treat. My second thoughts are that he should mind his own business! I think it's disgusting that he thinks it's OK to dangle it in front of you yet you have to cut out from your diet.
Was he flirting with you?
If you see him again next time you order cake, buy two slices and hide the second one in your bag when you sit down lol
