I provided $70, sayin git out loud, to the gas clerk named "Dabid", or "David" on Saturday, Oct 25 at about 1:15pm, since he said their ATM and Credit card pump machines were not working that afternoon. He did not provide me with a receipt. I pumped about $35 of gas, returned to him, and he gave me change for $60. I told I gave him a $50 and $20 bill, but he refused. I advised the cameras would have seen it, but he refused to play them. I asked his name, and he refused multiple times, eventually writing it down in illegable, to me, letters. I finally got it when his partner looked at him.
