We went out to eat some lunch. Long story short, the server gave the cocktail to the 15yo, but we really didn't notice until he had drunk half of it. It was for me BTW, and it didn't even cross my mind that I was drinking a mocktail! Manager realised, panics and then takes the half drunk cocktail away, and brings in another mocktail (but not cocktail). Service she as very slow and after the incident we felt like we were actively ignored. 3yo had to leave as service was so slow (his meal included an ice cream), but when they cleared the table they didn't ask if we wanted either more drinks or dessert.
When it came to pay, she expected for me to pay the who.amount which I thought was unacceptable, then offered a 10% (that didn't even cover the cocktail). Eventually we vmwe to an agreed but I was mega annoyed by then .
