Witnesses say he was very polite throughout the bank robbery that happened around 1:30 p.m. Friday.
The suspect entered the Amegy Bank located at 1801 Main in Downtown Houston. 
The robber waited patiently in line before being called up by the teller. He handed the teller a note announcing the robbery and asking for certain denominations of cash.  Then, he continued to repeatedly thank the teller and tell her how much he appreciated her assistance. 
He even provided the teller with a paper bag in which to put the cash. 
After exiting the bank with the cash, he ran south on Fannin Street. 
No one was hurt during the robbery.
