Well… If they remove it is to stay on the same price and avoid an increase or reduce the amount of increase. It cannot get cheaper…
They needed to increase it and this was to avoid it or to avoid a bigger increase.
To be cheaper that would require that the prices of the raw materials stayed the same which isn’t the case or I guess but I doubt it’s the case that they increased the prices of their products aka burgers but they saw the low sells and removed the tomato and reduced prices to increase sells.
They can reduce margins but that has nothing to do with the tomato removal and if needed they probably did reduce them up to certain point.
This is Burger King… This is not a bare necessity, they know of it gets expensive people simply won’t go. This is not like increasing the price of the raw food or monopoly product…were there is no alternative
