this kinda of reminds me of the dam dual lan drive thrus at mcdonalds. by design they encourage people to get pissy with each other because no one is actually in charge. the design flaw is in how mcdonaolds designed these drive thru's, not the customers.

The same is true here, Square has designed a system where people getting annoyed with others is the predicted result. They need to manage the process for an orderly log on, not us
