Ok, on a scale of one to ten how suspicious would this make you?

I have found a receipt from Tesco's for two bunches of daffodils. Dp claims he was indeed in Tesco's on the date shown but was buying WD40 and "must have picked up someone else's receipt"

? or ?

Suppose it comes down to is he

a) spending time with the bike - and using the WD40

b) riding off on the bike to heaven knows where and the WD40 is still in the Tesco bag unused a week after he bought it??
