Business versus pleasure

Issy owned a small deli in Hendon. One day, a tax inspector knocked on his
door and questioned him about his recent tax return. Issy had reported a net
profit of £50,000 for the year and he wanted to know all about it.
"It’s like this," said Issy. "I work like a maniac all year round and all of
my family help me out whenever they can. My deli is closed only five times a
year. That’s how I made £50,000."
"It's not your income that bothers us," said the taxman. "It's the business
travel deductions of £80,000 that worries us. You entered on the tax return
that you and your wife made fifteen business trips to Israel."
"Oh," said Issy, smiling. "I forgot to tell you that we also deliver."
