Angelique Sanchez, 26, reportedly left the convenience store before returning to clear up the mess with napkins after the store assistant called the police.

However, after she was taken for questioning she told the police officer she was due to take a urine sample for a drugs test later that day, but then denied it being a real sample.

The officer writing the police report said: ''When I reminded her that urine blew up where people prepare their food, she told me it was not real urine.''
