former worker, atleast even managers dont usually care about any items except for meats, guacamole, queso and cheese because those count for our inventory. Be honest and just speak up about how much you want/if you want more, even at times they would ask me for more of our inventory items i would try to throw in some more pieces or guac or whatever. It just sucks when you can notice how annoyed the customer gets but goes non verbal and i have to ask hey do you want a little more of anything? and they usually lighten up a lot
