Jones was able to escape and police only managed to track him down after members of the public reported what his car looked like, the Telegraph reported.
Prosecuting, Jane Waugh told the court: "The manager approached the defendant as he waited in the queue and asked if she could help him. He replied no."
Judge Christopher Prince questioned Miss Waugh about the manager's actions, adding: "So it was a hot day, he was wearing a coat with the hood up, carrying a big bottle of Febreze, wearing sunglasses, a facemask, blue plastic gloves and yet he was just observed as he made his way to the front of the queue where Victoria Smith was left to be threatened by a man who said he had a bomb and acid?"
After taking advice, Miss Waugh explained: "The manager was concerned he might have had a skin condition because he waited patiently in the queue. She went to speak to him to find out if everything was all right.
"She tread a careful line between upsetting someone who might have had to wear such things to protect their skin or have a nasty motive for wearing such a disguise."
Jones admitted the robbery and was jailed for 40 months by Judge Prince.
