Fickle folk, English, tucking into fruit after tea (10)

'fickle folk' is the definition.
(I've seen this before)

'english tucking into fruit after tea' is the wordplay.
'english' becomes 'E' (abbreviation).
'tucking into' indicates putting letters inside.
'fruit' becomes 'melons' (I have seen 'Juicy fruit ' mean 'melons' so perhaps 'fruit' could also mean 'melons').
'after' says to put letters next to each other.
'tea' becomes 'cha' (cha is a type of tea).
'e' placed within 'melons' is 'meleons'.
'meleons' put after 'cha' is 'CHAMELEONS'.
