My 2 Experiences
Tried to get a table of 4 at carmines nyc same day. After 30 mins CSR said couldn't help. Started to snow that day called I called restaurant and got in myself and place was pretty quiet for carmines.
Jayz NYE. Amex is sponser of barclays center called and told them I was seeing tickets still on ticketmaster if they could get better seats then what was showing. Told me it was sold out and broker was only option 100.00 more a ticket then stubhub for nose bleed seats.
Ended up last minute buying 1st row from stage almost 1/2 price from ticket price and same price as amex nose bleed seats. awesome concert and night.
