Customer Filter

I have data for customers and the amounts they have paid.

In the amounts column i have figures and word.

What i wish to do is exclude/ filter from the list customers which only say large in the amount column.

However the problem i have is some customer which also have figures which i do not wish to exclude.

So basically i what to look down the whole list of customers for j blogg ( example) and see in the corresponding amount column. if it says large on every
amount line then i want to exclude them from the list.
