This code is for Citigroup employees traveling on leisure, so you could certainly be asked if you work for the company. In some cases they may even ask for proof. It doesn't always happen, but if you do get challenged and cannot prove your eligibility for a particular discount code, then you may end up paying the walk-up rate which is far higher than anything you can book on-line with a "safer" discount code. If you need help getting a good deal on this rental with a discount code you don't need to sweat over, feel free to PM us.
