"I occasionally try to get the corporate rate for a company I'm visiting in the area (for sales/consulting). Only once has a front desk clerk asked me to prove my eligibility, and she was satisfied by me giving the name and telephone number of the person I was visiting."

"We know what the various Deloitte, EY, PwC, Google, Meta, etc badges look like. If you work for the company, it’s not a problem to verify that you work there. We do this for the random people that say they work for Deloitte, when in reality, they just refill the vending machine at a Deloitte office."
