Toasted bread for R50...?!

Why can the orders we exactly the same, it seems different cooks make the sandwiches different. One week I will order a toastie and it actually has filling on the bread, the next week I will order the exact same thing but will have no more than a teas**** of filling??? How does this work, there needs to be a standard for how much goes onto a sandwich not just how ever you please or according to your mood of the day... SERIOUSLY nearly R50 for basically 2 slices of bread. I am disgusted.
