Can a courier refuse to carry my food order?

Yes. Porter's terms say it may refuse any booking without giving a reason, and restricted items include dry ice, flammables, hazardous goods, cigarettes and alcohol.

• Goods are carried on a "said to contain" basis, with a declared value.
• Read your courier's own terms before you depend on it for a rush.
• Have a back-up, such as your own rider, for orders a courier turns down.
• Other couriers have their own rules.
