Last week was busy.
With Valentine's day on a Sunday and most areas having Monday off, it was the busiest your restaurant has been in months. Tuesday rolls around, and you need a day to recover, and Wednesday, you are getting caught up on all the stuff you forgot and Thursday, your back at it preparing for the weekend, and now it's Friday and your sick. Not from drinking too much but from looking at the books and noticing this weekend will not be as busy as last weekend.
You never posted, never sent out an email, now you scramble. You start to panic a bit and think, what have I been doing all week.
This is why it is essential to have your marketing communications pre-planned. Automated., Evergreen. This way, if you decided to take a minute, the foot still stays on the gas. The sales funnel is always being filled with new contacts, and those contacts are becoming paying guests.
