"Do not use microsoft at the mariott marquee in times square without having a basic spoofed email showing a microsoft domain to the front desk. only place I have ever been asked for proof. Across multiple companies and property tiers"

"I mean, when I worked night audit, the whole night is practically a break after like 1am. It was usually just me and one other guy running the place (the other guy is just cleaning and doesn’t know how to do front desk). We don’t get an actual “lunch break” where we have to clock out for 30 minutes because we can’t leave the desk completely unoccupied (unless you were going to the bathroom or tension to a guest away from the desk or something). And we just ate at our desks if we were hungry, not sitting in the back."

"My last couple of corporate RFID cards had no company name on them for security purposes. My current company doesn’t do business cards. I use my Bonvoy card for corporate travel to get the points. I’d have to write them an email standing at the check in desk, I guess."
