During my last visit to Costa Coffee I ordered a hot drink for myself and a cold coffee drink for my daughter and as she was drinking it she kept getting little bits of white plastic through the straw onto her tongue and when she looked at the bottom of the cup there were larger bits of white plastic we think it looked like parts of a plastic top that had somehow been mixed up when they were preparing her cold drink. This was very worrying as her small son likes to have a little sip of coffee as he loves the taste and could have choked on it. I purchased the drinks at the Costa Coffee at the Albert Dock. I await your speedy reply. Sandra Jervis
