It's not delivery
I have a small, homemade, fold-away reflector oven [cookie sheets and steel rods] that I can prop up in front of the fire. Cooking pizza while campers are making their final rounds or walking the pets always elicits comments - 'do you smell pizza?' 'I smell pizza' ' No, it can't be, not way out here' 'It must be something else that smells like...' 'I didn't know there was a pizza place near here.' etc....
Sometimes there are comments during morning ablutions - 'Did anyone smell pizza cooking last night?' etc....
