Difference between push and pull marketing 21st Century marketing tools

Here's the difference between push and pull marketing.

Went to Dillard's today. Strolled around, looked at the merchandise. A polite clerk said may I help you? No. Went on shopping and purchased.

Right next door was an auto sales tent event. Walked in. Can I have your name?

I'd just like to look around.

I'll get a salesperson for you to look around.

I just wanted to look around.

You can't do that without a salesperson.

Okay, goodbye.

A lost sale - and it probably would have been a sale. Pull marketing wins over push.
