I would like to report that my superpower - invisibility worked twice this week 
For a short moment.
1. I went shopping yesterday at Lidl where I work. I said hello to cashier, she started to scan my shopping, and continued chatting with herself, and next and previous customers. She didn't notice me at all until I handed her my colleague discount card, than she admitted she didn't recognise me. Yes. Almost total success.
2. Today while I was smoking in the entrance to the building, and reading a book, one of neighbours turned around corner, and didn't notice me until she made 5 steps, than she jumped up startled saying she didn't notice me. Again almost 100% success.
It seems it works sometimes even without my ''I'm invisible. You do not see me'' hand waving.
