Costa Coffee - Hull Paragon Interchange in Kingston upon Hull, City of

A mistake with milk alternatives was made, I asked for oat however with the plastic screens everywhere meant the cashier must've misheard. I couldn't take the two lattes because of the dairy allergy, I offered to pay the extra for the new milk. The attitude and glare I got from women making the drinks was disgusting. I work in hospitality myself and know that mistakes are made just part of the job, so for the reaction from her was unacceptable. The actual cashier was really polite and apologised. (Not only that her hair was down, I know that working with food and drink this is really unhygienic)

Stopped here for a drink before travelling. Friendly staff and fast service. Summer drinks menu is available here and is worth trying.
