Well, its $18 for a hot dog and a drink, and also the cost of labour and transport to get them to your door, and little bit for admin costs.

So if, say, the delivery person can do one every 20 minutes, that's $54 of revenue an hour for the company, minus, say, $10 for the actual food/drink items, $20/hr to employ the person, plus 3 x trips at, say, 5 miles per trip at like, 25 cents/mile for fuel and maintenance, so $3.75 for that.... so about a 80-100% markup on cost for basic labour and expenses, which is where businesses generally need to be on markup to keep afloat.

The other option is to go get one yourself I guess, but if you value your time the costs end up being approximately the same.
