Sushi is pretty quick to make, and maki rolls moreso. It tends to be a high margin item due to a high price. A sushi order with $10 of profit can be delivered for $5. A few snacks with a profit of $1 cannot be delivered for $5. Maybe you can shrug and just pay a higher delivery cost : item ratio to make it happen anyway. But in my area the reason the asian restaurants are only faster is because they have their own dedicated delivery staff. That would just not work for random convenience stores because the order volume is low due to stupid prices. Margin $, Margin %, Transportability and Order Volume are the big ones in my guesstimate. Pizza is the ultimate choice across those 4. I don't think asian restaurants are better at this across the board consistently.
