what does "draw back" in this sentence mean ?
Jonathan insisted on paying, so he went to the store and bought something he didn't need to make change. But when he gave the money to the vendor, the vendor drew back. He was hurt. He was trying to do something kind, but Jonathan had rejected him.
This is from a TED talk, and I am a bit confused with the meaning of " draw back" here. does it mean the vendor turned down the money or the vendor moved a step back physically ?
Thanks a lot :)
