Perth's accused dine-and-dash scammer will remain behind bars for now, after another failed bid for freedom.

Lois Loder is facing more than 150 charges including stealing and fraud and is accused of ripping off dozens of restaurants.

Prosecutors said the "vast majority" of the charges were committed while the 44-year-old was on bail.
