Cheap-otle?

mage from Chipotle.

One of my favorite foods is a burrito.  One of my favorite places to get a burrito is Chipotle. Their food is delicious and environmentally friendly.

For Halloween 2016, Chipotle ran a promotion and charity drive.  Chipotle offered $3 burritos to customer who come dressed in their Halloween costumes after 3 p.m. on October 31st.  Chipotle hoped to donate up to one million dollars to their foundation.

• How realistic is it for Chipolte to sell one million dollars worth of $3 burritos in one night? 

• What more information would you like to have to decide if this is even possible?
