1) Spending more during a sale
It is not gender specific. Really. Both men and women make impulsive purchase and this happens more often during sale & discount, and especially when people feel that they are getting something for Free (Hurray!). But by the time you are done with shopping, you probably only really wanted 6 of the 10 items you have purchased. Discount? What discount?
So the next time you see a big red sign stating One for One, avoid it unless you actually really want it. Or you may end up with TWO tops that you hate and which would simply take up space in your wardrobe.
2) Spending more, on something that you do not actually want.
More than once, I have met with almost death stares when I order bottled drinking water or willingly pay for water at restaurants.
Afterall, why would anyone pay for something that is ‘free’? So within that short few seconds of being told that water costs money, some of us would feel dissatisfied and go through a new round of decision-making; “WHAT? why should I pay for water? I’d rather pay for a proper drink. That’s fairer.” and to finally ordering a drink which we may not necessarily want, but which we are comfortable in paying for.
That is, we end up spending more on something that we do not actually want.
So really, if you are not the owner of the restaurant, try not to be too affected by their margins. Focus on what matters: know what you want and is willing to pay for it. And when this is clear, you will know exactly what to buy when the sale is going on.
