Always be nice.

I was reading about the recent saga of ladyironchef food blogger's arrogant and assuming behavior.
Mistake 1: Who gives you the title of a food blogger? Did you earn an education in gourmet studies. If not, according to my own definitions, i can be a food blogger too. And bonus point, i am prettier than you for sure.
Mistake 2: When someone invites you for a food tasting session, with the goodwill of accomodating another guest, you don't end up bringing 3 friends and expect to taste for free. You are not going to a wedding or a feast. Even wedding invitations, we pay! Wake up your idea, dude.
Mistake 3: Your words as a food blogger has no stand at all. One man's meat is another man's poison. After reading your food reviews, i suspect amateur is your middle name.
Mistake 4: If you are there for a food tasting, how does the wine come into the picture. If all food tasters, or rather food bloggers get free wine, clubbers will find their new green pastures.
Mistake 5: Don't ever throw credit cards at waiters when paying your bill. They are not your slaves, and you are not their lord. Seriously, they don't owe you a living.
Mistake 6: You are not a food connoisseur, not even near that, so cut the arrogance and ego.
Mistake 7: Never blog about your apologies. It does no help at all. Damage done, face it.
Always be nice. Nomatter your status ( and you didn't even have one to begin with).
