Restaurants and bars especially in my city love tax evasion - that's why they are so enthusiastic about cash payments.

Yes thats normally the main drive, cash is usually just annoyance and additional risk to business.

I wouldnt be too harsh judging that business though, quite a few restaurants are barely cutting it so this may help them stay afloat. Its this or generally higher prices in restaurants.
