Caffeine makes you spend more money on shopping.

Drinking caffeinated drinks before and during shopping - coffee, tea, energy drinks, hot chocolate - makes people spend more money and buy products that bring pleasure: for example, home decor. American scientists came to such conclusions after five experiments involving almost 800 people. The researchers analyzed the receipts of customers who used caffeine before shopping and those who drank drinks without caffeine. This effect of caffeine is seen in those who drink less than two cups of coffee a day. In people who drink more, it weakens.
