David S. and Stephan T. were impressed by several differences between Gibraltar and Spain during a school trip. They noticed Gibraltar used British pounds while Spain used euros, Gibraltar's telephone boxes were red and closed off while Spain's were blue and open, and monkeys in Gibraltar were entertaining but naughty while the largest monkeys were ugly and smelly. They also saw differences in policemen's uniforms including funny hats, and prices for items like tobacco and alcohol were lower in Gibraltar than Spain.
