i bought a bag of six golden wonder (so much better than greasy walkers) salt and vinegars the other day, now I know the TLs daughter will try to eat them if she runs out of her own so I keep a big bag (empty) of aldi Mccoy rip off crisps (that she would never eat, being young) and i pop the Golden Wonders in that as a cloaking mechanism and hey presto my crisps go untouched
