Subway complaint: Made how they want

When I went into the store today to order 3 sandwiches, I was told that my 2 years old needed to get off of the chair that she was using to look at the toppings in order to maintain a distance, I was told that I couldn’t have toppings put onto my sandwich how I like them because she was training the other person to make it correctly (I don’t like spinach to go on before tomato and cucumber because when I take a bite it pulls the other toppings out, so I opted to leave out the spinach), she completely forgot about my third sandwich and I asked for the flatbread and bacon to be heated separately so she only did the bacon and it was missing pickles and mayo that I asked for. Granted I should have paid more attention to the last one but it was kinda hard to make sure it was correct when I was being rushed to pay so they could ring the person behind me
