Who wrote the sample query? If I was trying to "Compare Chipotle’s sales performance to that of McDonald’s", my query would not start with "SELECT *". There would be some meaningful columns.
Yeah that's fair. The tables are all in an EAV format (narrow), so the number of columns coming along here is very small (you would filter for Chipotle/McDonalds in your WHERE) but it is fair that that sample query could be more instructive / better practice to name columns.
