Здравствуйте,

У меня проблемы и сомнения с глаголом "Хватать".

Should one say "У меня не хватает на такси" или "Мне не хватает на такси"?

Also, may I use "хватит" instead of "хватает" in the above example? Are the verbs usually interchangeable - the only difference being the aspect?

Would you be so kind as to expand a little on the matter so as to clarify the situation? I should like to be quite sure of how and when to use them.

Thanks.
