Not to change the spare bed sheets for a new guest

[Orangedaisy]

Would never dream of doing this normally. Very clean MIL coming for 1 night. The week after DP's friend is staying for 1 night, by the time he gets to bed he'll be pretty drunk if usual behaviour is repeated. It fills me with horror not to have a spotless bed/bedroom for guests but really not sure I can be bothered this time. WIBU not to change them as a one off?

Pop a candle and some toiletries in the room ?

Wow !

Complete waste of time , electricity and water to changed the sheets in these circumstances.
Scabies notwithstanding
