You're at someone's house-party. There's a line-up of anxious people waiting noisily to get in. You flush a number of times (not too many lest they think you're a pervert) but sizeable pieces of thing refuse to go down. What's the politically correct etiquette here?

1. Cover your head with the shower-curtain and emerge with a rush?
2. Grab at it (them) with toilet paper and put them in the cistern?
3. Put down the lid and cover it with shampoo bottles, hair-spray, tampons, Optrex etc. in the hope that you can be in another time zone before the next in line opens it?
4. Other?
