Check the price tag before grabbing a bottle of ketchup for your barbecue

It's easy to reduce the amount of ketchup in the US.
The first way is to abolish free ketchup service.
Some stores like Arby's are serving ketchup for free. It can accelerate more consumption of ketchup than needed.
The second way is to reduce the amount of ketchup when restaurant staff pass ketchup to customers.
In such a situation, I often receive 5 or 6 satchets of ketchup. It's obviously too much.
