Ba left his former car cleaner raging after leaving Newcastle for Chelsea without settling his £40 bill, according to the Daily Mail.
He completed a job on Ba's gold Mercedes 6.3 before Christmas but claims he is still owed £40 by the Senegalese striker who is reportedly on £90,000-a-week.
Speaking to the Evening Chronicle, he said: "It’s the principle more than anything. I asked him a few times for the cash and he said, "I owe you still" but last time I saw him he said he only had a £50 note.
"I didn’t have any change so he just put the £50 back in his wallet and said it would have to be another time and drove off. I thought for the money you’re on why don’t you just give me the £50 for messing me about."
