EVERYONE, preggers or not, are allowed hot chips, with salt, AND hosed down in vinegar (for me anyhow) just once in a while
LOL yep a month or two ago i got hot chips drowned in vinegar on my lunch break, they were so soaked that the bottom fell out of the chip box as i walked back to work and about 10 seagulls swooped in and ate them all
funniest bit is i went back to the shop and told them 'i dunno why, the box just collapsed' and got a replacement...the paper box this time wrapped in a plastic bag ....pmsl
