My lovely 18 year old DD works in a smart Cotswolds gastropub. But this would be grim anywhere to be fair. So today a family comes in for lunch. Sit at table in main part of pub. In another part of the pub there is a table set for 21 for a later lunch but empty at that time. Family ask if their kids can have a nap there. DD replies no sorry as it is all set for lunch and the other party would be arriving soon. (Kids not in pushchairs btw). So the family eat lunch and leave. During the lunch she notices parents changing childs trousers - at the table! But she is too busy with other customers to say anything. After they leave, another customer tells DD she saw their kid wet their pants on their chair. DD goes over to their table and sure enough finds soaking wet chair just left. There is a loo with a baby change just nearby!
DD says that this kind of thing is common. Parents typically leave a huge mess, used nappies under the table, etc. And people wonder why waiting staff don't like kids!
One family left the table where their kid had vomited under the table and didn't alert the staff - apparently it had gone everywhere.
DD understands that these things happen - but surely you tell someone, don't just leave it? And maybe an extra tip?! And you definitely don't strip a toddler in the middle of a restaurant?!
