Yeah I know, I'm a grumpy old woman but... there is this woman at work who can not stop sucking every single finger of her hands, I have counted more than 50 nnoisy sucking noises at eating a humble packet of crisps. Fordet about when she eats cake or any other more sticky stuff.
Anyways, I had to cover for her a few days ago and sit at her desk and use her computer... The keyboard and mouse were so sticky I felt the need to get a packet of desinfectant wipes to clean it a bit before laying my hands on it, it was full of jam and cheese crisps powder stuff. There was saliva on the screen and even the chair was covered in true white marks were she wipes her hands after cleaning them in her mouth.
From time to time she likes to use my computer and I can immediatly notice if she has done so (jam, crisps crumbles and other sticky stuff on my keyboard, mouse and desk). To make the things worse she is always down with one bug or another one so, the saliva spreading is getting on my nerves.
How do I go about telling I don't want her to use my computer without offending her (or she backfiring giving a good lick to my computer as a revenge?
