Totally offended by the shop assistant and his minor

<p>I went to vergelegen plein to buy flea products for my dogs, and after telling the shop assistant that i dont want to use a certain product, he became so offensive and telling me to get my facts straight. His minor kid started saying everything he said in repeat and told me not to trust the internet as if im a toddler! I have graduated with a university degree and being told by a shop assistant's kid what to trust and do, it was so humiliating and felt really offended by allowing his kid to talk to me as a child! I kept quiet as i was shocked how they just kept going on and thinking they are learning me a lesson for information i already know insinuating that im stupid. The shop assistant allowed his kid to talk with disrespect toward an adult. Unfortunately i just listened to the unwanted "information"</p>
