A Nando's worker was caught with heroin and crack cocaine after police noticed smoke coming out of his car bonnet, a court heard.
Muhidin Mukhtar, 24, was stopped by officers in Moss Side as they were also 'concerned' about his speed.
They noticed there was a 'large amount of smoke' coming from his bonnet.
Police noted Mukhtar appeared to be under the influence of alcohol, and he failed a road side breath test.
When he was taken to Longsight police station, he was found to have 28 wraps of heroin and 28 wraps of crack cocaine stuffed in his trouser leg.

The heroin was said to be worth £560, and the crack cocaine was valued at £280.
He also had a 'burner phone' which included messages about drug dealing, prosecutor Philip Hall said.
Prosecutors said they accepted Mukhtar was acting as a 'courier', acting on the orders of superiors.
After being arrested, Mukhtar told police he had been using heroin and crack cocaine himself, spending about £200 to £300 a week on his habit.
Mukhtar later pleaded guilty to two counts of possessing a class A drug with intent to supply.
The incident happened in August 2018.
Manchester Crown Court heard police only passed a file to the Crown Prosecution Service in October last year.
Judge Alan Conrad QC said the delay in the case would 'impact on sentence'.
"It is wholly wrong that really straightforward cases like this take so long to investigate and pass on," the judge said.
"It shouldn't be happening."
Defending, Thomas McKail said Mukhtar has since turned his life around, and has obtained employment working for Nando's.
He said the defendant had been furloughed but he is set to return to work in October.
Judge Conrad said he would defer sentencing for six months.
He told Mukhtar that if he stayed out of trouble, then he would likely avoid jail.
"It's going to be up to you," the judge told him.
"If you comply with my conditions it is highly likely I won't send you to prison."
Mukhtar, of Regent Avenue, Moss Side, will appear in court again in February next year.
