You've seen it in your personal life:
When someone gives you a gift, does you a favour or is continually nice to you...
… You feel an urge to repay them in some way.
Your customers feel the same as YOU.
And here's why:
The urge is down to RECIPROCITY and most of us fall for it...
… "I'll get the next round of drinks."
… "It's our turn to invite you round."
… "We can't go round to them and turn up empty-handed."
So start giving your customers surprise Thank You gifts. Exceed their expectations. Show them you value them. You'll be amazed how they repay.
Treat customers as individuals (not as numbers) and you'll enjoy all the benefits reciprocity brings.
