Asking for a date

Hi,
I am living in Sweden but I am originally from another country.
I am interested in a girl who is working at ICA. I mean I have seen her at ICA.
My question is: is it proper to ask her for a date in her work place?( because there is no other choice to meet him outside of her work place.)

please anyone from Sweden answer my question.

best

Subtle is always good if you really like a lady.

Leave a box of chocolates on her desk with a note asking if she'd like a coffee.
