It is well known that one of the biggest mistakes that people do when grocery shopping is to be on an empty stomach and that's because everything seems tempting and so delicious when you are hungry.
As a result, you end up buying things that you don't need and foods that ain't even on your shopping list and when you get to the cashier, you pay double and ruin your budget.
So if you are going to the supermarket for grocery shopping and you don't have time to eat, chew a gum especially peppermint gum and keep it in your mouth while shopping.
Chewing a gum helps you counteract the effect of ambient scents in stores and peppermint chewing gum in particular satiates hunger and helps block out other scents.
