2 Tantrums are a fact of life when you live with a toddler.
Frustration is also a big tantrum-trigger.
If you know your toddler is going to insist on visiting the pet store when you go to the mall, make sure you have time to do it, or think twice about the trip. This isn't really giving in to your child, it's just predicting how he's likely to react and thinking through the consequences and alternatives. Of course, avoiding a tantrum isn't always possible. Once one starts, it's hard to reason with your toddler. If you find his public tantrum embarrassing, your best move is to leave.
