Another technique restaurants use is the set menus, which can end up costing customers more money. How?
“Many diners opt for the set menu as it feels like you’re getting more bang for your buck, however, this tactic can actually make you spend more money than you would have should the set menu not be an option. Whilst a three-course menu for £20 may seem like a bargain, you may not be that keen on the starter or dessert options but choose them anyway.
“Instead, opting for a £12 main course and £5 dessert, both of which you really like, works out better,” Andrea explained.
In restaurants, appetisers are often served in odd-numbered portions to create a common problem.
