A man staying in digs, because his work was far from home, asked the landlady if she would provide him with sandwiches, for his lunchtime break.

On the first evening, after work, the landlady asked him, "Well how was your lunch?"

The man replied, "It was very nice. I like cheese, but there was only two slices of bread."

The landlady made up his lunch for the next day with four slices of bread.

After work, she asked him, "Well, how was your lunch today?"

He replied, "It was very nice, but there wasn't very many slices of bread."

The landlady, a bit peeved, made up his lunch for the next day, by slicing a plain unsliced loaf in two, down the middle. Then she stuffed a whole block of cheese between the two pieces of bread.

After work, she asked him, with a cynical smile on her face, "Well, how was your lunch today?"

He replied, "It was very nice, but I see you are back to the two slices again.
