The incident, which is both reported to the police and reported to the Swedish Work Environment Authority, took place about a week ago.
The man was masked with a scarf for his mouth and nose and had a hat and hat that was pulled down a long way.
At first the shop assistant did not react - it was cold outside.
- He gave his name and I picked up the package, but when I asked for identification, he tore away the plexiglass and sign material and tore the package to himself, says Maria Karlsson.
Insecure industry
The report states that she jumped backwards to avoid the man when he threw himself under the plexiglass.
According to Maria Karlsson, this is an example of how insecure it can be in trade.
She works for the trade and service industry's metoo call for safer workplaces, especially for women and non-binaries.
- We hope that the government will get the law that we will be able to port difficult customers to make it safer, says Maria Karlsson.
